A solution of L-phenylalanine in acetone was added dropwise to a two-necked round-bottomed flask containing an equimolar solution of 2-methylbenzoyl isothiocyanate in distilled acetone. The mixture was refluxed for about 5 h to complete the reaction. The resulting solution was poured into a beaker containing some ice cubes. The white precipitate obtained was filtered and washed with distilled water and cold ethanol before dried under vacuum. Good quality crystals of (I) were obtained by recrystallization from methanol (yield 81%, m.p. 385.2–386.4 K).
After their location in the difference map, all H-atoms were fixed geometrically at ideal positions and allowed to ride on the parent C, N or O atoms with C—H = 0.93–0.97 Å, N—H = 0.86 Å and O—H = 0.80 Å, with Uiso(H)= 1.2Ueq(C, N) and 1.5Ueq (Cmethyl, Ohydroxyl).
The title compound, (I), is an amino acids derivative of thiourea and analoguos with 2-[3-(4-methoxybenzoyl)thioureido-3-phenylpropionic acid methanol solvate, (II), (Ngah et al., 2005), except that the position of methyl group at the phenyl ring (Fig.1). The molecule maintains its trans-cis configuration with respect to the positions of 2-methylbenzoyl and 3-phenylpropionic acid relative to the S1 atom across the C8—N1 and C8—N2 bonds, respectively. The bond lengths and angles are in normal ranges (Allen et al., 1987) and are comparable to those in (II). The central thiourea (S1/N1/N2/C8), 2-methylphenyl (C1–C6/C20) and phenyl ring (C11–C16) fragments are essentially planar with a maximum deviation of 0.041 (2) Å for atom C7 from the least square planes. The dihedral angles between the central thiourea and 2-methylphenyl fragments is 55.40 (7)°.
There are three intramolecular N—H···O, C—H···S and C—H···O hydrogen bonds, (Table 2), and as a result, a pseudo-five- (S1···H9—C9—N2—C8—S1) and two pseudo-six membered rings (O1···H2—N2—C8—N1—C7—O1), (O1···H20—C20—C5—C6—C7—O1) are formed. In the crystal structure the molecules are stabilized by intermolecular O—H···S, N—H···O and C—H···O hydrogen bonds, (Table 2), forming a one-dimensional chain along to a axis (Fig.2).

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

The title compound, (I), is an amino acids derivative of thiourea and analoguos with 2-[3-(4-methoxybenzoyl)thioureido-3-phenylpropionic acid methanol solvate, (II), (Ngah et al., 2005), except that the position of methyl group at the phenyl ring (Fig.1). The molecule maintains its trans-cis configuration with respect to the positions of 2-methylbenzoyl and 3-phenylpropionic acid relative to the S1 atom across the C8—N1 and C8—N2 bonds, respectively. The bond lengths and angles are in normal ranges (Allen et al., 1987) and are comparable to those in (II). The central thiourea (S1/N1/N2/C8), 2-methylphenyl (C1–C6/C20) and phenyl ring (C11–C16) fragments are essentially planar with a maximum deviation of 0.041 (2) Å for atom C7 from the least square planes. The dihedral angles between the central thiourea and 2-methylphenyl fragments is 55.40 (7)°.
There are three intramolecular N—H···O, C—H···S and C—H···O hydrogen bonds, (Table 2), and as a result, a pseudo-five- (S1···H9—C9—N2—C8—S1) and two pseudo-six membered rings (O1···H2—N2—C8—N1—C7—O1), (O1···H20—C20—C5—C6—C7—O1) are formed. In the crystal structure the molecules are stabilized by intermolecular O—H···S, N—H···O and C—H···O hydrogen bonds, (Table 2), forming a one-dimensional chain along to a axis (Fig.2).
