Participants

Reaction Steps

To a solution of methyl 5-(2,4-bisbenzyloxyphenyl)-6-cyclohexyl-4H-thieno[3,2-b]pyrrole-2-carboxylate (1.12 g, 2.03 mmol) in N,N-dimethylformamide (10 ml) was added sodium hydride (60% in oil, 97 mg, 2.43 mmol) under ice-cooling and the mixture was stirred for 10 min. (2-Bromoethoxymethyl)benzene (0.53 ml, 3.24 mmol) was added and the mixture was stirred at room temperature for 4 hr. Ethyl acetate (25 ml) was added to the reaction mixture, and the organic layer was washed successively with water (20 ml×3) and saturated brine (10 ml), and dried over sodium sulfate. After filtration and concentration, the obtained residue was purified by silica gel column chromatography (hexane:ethyl acetate=5:1-2:1) to give methyl 4-(2-benzyloxyethyl)-5-(2,4-bisbenzyloxyphenyl)-6-cyclohexyl-4H-thieno[3,2-b]pyrrole-2-carboxylate (1.21 g, yield 87%).
