Procedure

A solution of 1-[(2-benzothiazolyl)thiocarbamoyl]imidazole (2.1 g, 8 mmol) and 2-(2-chlorophenyl)-ethylamine (1.25 g, 8 mmol) in N,N-dimethylformamide (30 mL) was stirred at 100° C. for 1.5 h, the reaction was cooled to room temperature and the solvent removed in vacuo. The residue was crystallized from ethyl acetate to provide 1.6 g (57%) of the title product:
