Procedure

A solution of 1-(2-[2-methoxyphenyl]ethyl)thiocarbamoyl imidazole (0.52 g, 2 mmol) and 2-aminopyridine (0.19 g, 2 mmol) in N,N-dimethylformamide (5 mL) was stirred at 90° C. for 4 h, the reaction was cooled to room temperature and the solvent removed in vacuo. The residue was crystallized from ethyl acetate to provide 0.25 g (44%) of the titled product: IR (KBr, cm-1) 3219, 3048, 1607, 1557, 1236, 1036, 756;
