A solution of o-fluoroaniline (1.11 g, 0.01 mol) in acetone (50 ml) was added dropwise to an acetone solution (50 ml) containing an equimolar amount of 3-chloroacetylacetone and ammonium thiocyanate in a two-necked round-bottomed flask. The solution was refluxed for about 2 h. The light-yellow solution was filtered off and colourless crystals of (I) were obtained after evaporation for 5 d (yield 85%; m.p. 447.8–449.3 K).
All H atoms were located in a difference map. The H atom on N1 was refined isotropically. All other H atoms were fixed geometrically in ideal positions and allowed to ride on their parent C atoms, with C—H distances in the range 0.93–0.96 Å and with Uiso(H) = 1.5Ueq(methyl C), or 1.2Ueq(C) for CH groups.

The title compound, (I), is isostructural with 5-acetyl-4-methyl-2-(o-toluidinyl)-1,3-thiazole (Yamin et al., 2005), except that the F atom is bonded at the ortho position of the phenylamino fragment. The whole molecule is essentially planar, with a maximum deviation for atom C12 of 0.127 (3) Å from the least-squares plane; in the molecule of 5-acetyl-4-methyl-2-(o-toluidinyl)-1,3-thiazole, the benzene group is inclined to the thiazole ring by 73.44 (10)°. All bond lengths and angles are in normal ranges (Allen et al., 1987) and are comparable with those in the analogue.
There are weak intramolecular N1—H1···F1, C10—H10B···O1 and C5—H5···N2 hydrogen bonds (Table 2) in the molecule. In the crystal structure, the molecules are linked by intermolecular N1—H1···O1i and C12–H12C···F1ii hydrogen bonds (symmetry codes as in Table 2) to form one-dimensional zigzag polymeric chains parallel to the b axis (Fig. 2).
