Ammonium dithiocarbamate (0.444 g, 4.03 mmol) was added to 2-bromo-1-(4-pyridinyl)-1-ethanone hydrobromide (1.03 g, 3.67 mmol) in ethanol (10 ml and stirring continued at room temperature for 18 hr. The solid was filtered and re-crystallized from methanol to give 4-pyridin-4-yl-thiazole-2-thiol. This thiol (272 mg, 1.39 mmol) was then coupled with N1-3-chlorophenyl)-2-chloroacetamide (284 mg, 1.39 mmol) as described in earlier examples, in acetonitrile in the presence of triethylamine (0.580 ml, 4.2 mmol) to afford crude product. This was purified by reverse phase HPLC to afford N-(3-Chloro-phenyl)-2-(4-pyridin-4-yl-thiazol-2-ylsulfanyl)-acetamide. MS (ES) 363 (M+H)+
