Reaction Steps

To a solution of 2.0 g of 6,7,8,9-tetrahydrothieno[3,2-b]azocin-5(4H)-one in 20 ml of dimethylformamide was added 1.3 g of potassium t-butoxide under ice-cooling and stirred at the same temperature. To the mixture was added 2.0 g of 1-bromo-4-chlorobutane and stirred at room temperature for 5 hours. The mixture was poured into water and extracted ethyl acetate. The extract was washed with water, dried over anhydrous magnesium sulfate and concentrated in vacuo. The residue was chromatographed on a silica gel using a chloroform as an eluent to give 2.8 g of 4-(4-chlorobutyl)-6,7,8,9-tetrahydrothieno[3,2-b]azocin-5(4H)-one as a pale yellow oil.
