The title compound, C10H8N2OS, features a nonplanar molecule [dihedral angle between the two aromatic rings = 43.6 (1)°]. Two molecules are linked by N—H⋯N hydrogen bonds about a centre of inversion, giving rise to a hydrogen-bonded dimer.

The synthesis uses microwave radiation, which compares with benzoylation by reacting benzoyl cyanide in an ionic liquid: see: Kumar et al. (2007); Prasad et al. (2005).

2-Aminothiazole (1 g, 10 mmol) and benzoyl cyanide (1.31 g, 10 mmol) were stirred together without any solvent for 3 h at 323 K. The oily product was purified by recrystalization from ethanol (yield 1.97 g, 90%); m.p. 383 K.
Carbon-bound H-atoms were placed in calculated positions (C–H 0.95 Å) and were included in the
in the riding model approximation, with U(H) set to 1.2U(C).The amino H-atom was located in a difference Fouier map, and was freely refined.
