A suspension of imidazole-4-carboxamide (313 mg) in DMF (3.8 ml) was treated with sodium hydride (60% in mineral oil, 129 mg) at ice-bath temperature and the mixture was stirred at room temperature for 20 min. A solution of 2-[(3S,4S)-4-benzyloxy-3-methanesulfonyloxypentyl]thioanisole (0.92 g) in DMF (7.5 ml) was added and the mixture was stirred at 85° C. for 3 days. The mixture was poured into water and extracted with ethyl acetate. The extract was washed with water, dried and concentrated in vacuo. Column chromatography (dichloromethane:methanol=30:1) gave 1-[(2S,3R)-2-benzyloxy-5-(2-(methylthio)phenyl)-3-pentyl]imidazole-4-carboxamide (1) (96.4 mg, 11.6%) as a pale yellow oil.
