Reaction Steps

A solution of 1-piperidin-4-yl-1,3-dihydro-benzoimidazole-2-thione (0.2 g, 0.84 mmol) in methylene chloride (20 mL) was treated with pyridine (0.040 mL, 0.497 mmol) and 4-n-butylbenzoyl chloride (0.093 mL, 0.497 mmol). The reaction mixture was stirred for 18 h then purified directly by column chromatography on silica gel using ethyl acetate as the eluent to give (4-butyl-phenyl)-[4-(2-thioxo-2,3-dihydro-benzoimidazol-1-yl)-piperidin-1-yl]-methanone (0.167 g; 86%).
