A solution of 2-(2,6-difluorophenyl)ethylamine (0.43 g, 2.7 mmol) and 1-[(2-pyridyl)thiocarbamoyl] imidazole (0.55 g, 2.7 mmol) in N,N-dimethylformamide (20 mL) was stirred at 90° C. for 27 h. The reaction was cooled to room temperature, poured into ethyl acetate, washed with water, 1N aqueous HCl, water, saturated sodium bicarbonate, and brine. The organic layer was concentrated and the resultant oil was purified by chromatography on silica gel to provide 0.08 g (10%) of the titled product as a pale yellow solid:
