The title compound was prepared according to the method of Kaiser & Thurston (1951). 2,4,6-Trichloro-1,3,5-triazine (40.0 g, 0.217 mol) was dissolved in toluene (120 ml) and then cooled to 278 K. With stirring, a solution of 2,4,4-trimethylpentan-2-amine (27.5 g, 0.213 mol) in toluene (50 ml) was then added dropwise to the mixture over a period of 0.5 h. Then a solution of Na2CO3 (23.02 g, 0.217 mol) in water (50 ml) was then added dropwise for 0.5 h. The mixture was stirred at 273–278 K for a further 3 h. Propan-1-amine (12.80 g, 0.217 mol) and solid Na2CO3 (23.02 g, 0.217 mol) were added to the mixture, maintaining the temperature at 338 k for 5 h. The title compound (52.18 g) was obtained in powder form in a yield of 80.2%. Crystals of (I) were obtained by slow evaporation of a solution of methanol.
Both alkyl side chains are disordered over two positions, in a 0.5:0.5 ratio for the tert-butyl containing side chain, and a 0.592 (8):0.408 (8) ratio for the n-propyl chain (occupancy sum for the latter constrained to unity).
The H atoms were positioned geometrically (N—H = 0.86 Å, C—H = 0.96–0.97 Å), and refined as riding with Uiso(H) = 1.2Ueq(carrier) or 1.5eq(methyl C).
The title compound, (I), is an important intermediate of hindered light stabilizers (Borzatta & Carrozza, 1991). The triazine ring in (I) is essentially planar with an r.m.s. deviation from the mean plane of 0.0173 Å. Both alkyl side chains are disordered. The crystal packing is consolidated by N—H···N hydrogen bonds (Table 1).

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 important intermediate of hindered light stabilizers (Borzatta & Carrozza, 1991). The triazine ring in (I) is essentially planar with an r.m.s. deviation from the mean plane of 0.0173 Å. Both alkyl side chains are disordered. The crystal packing is consolidated by N—H···N hydrogen bonds (Table 1).
