Reaction Steps

To a mixture of ethyl 1-[(2S,3R)-2-(tert-butyldimethylsilyloxy)-5-methanesulfonyloxy-3-pentyl]imidazole-4-carboxylate (160 mg, 0.368 mmol) and 2-naphthalenethiol (118 mg, 0.736 mmol) in DMF (5 ml) was added potassium carbonate (102 mg, 0.736 mmol) at room temperature and the reaction mixture was stirred for 2 hours. The resulting reaction mixture was poured into water (25 ml) and extracted with ethyl acetate. The organic layer was washed with brine, dried (sodium sulfate) and evaporated in vacuo. The residue was purified by silica gel (10 g) chromatography eluting with chloroform/methanol (100:1 to 50:1) to give ethyl 1-[(2S,3R)-2-(tert-butyldimethylsilyloxy)-5-(2-naphthylthio)-3-pentyl]imidazole-4-carboxylate (146 mg, 79.5%).
