Reaction Steps

To a stirred solution of 1,1′-(4,5-dihydrobenzo[b]thieno[2,3-d]oxepine-2,8-diyl)bis(2,2-dibromoethanone) (2d) (0.65 g, 1.08 mmol) in 20 ml THF at 0° C. was added Et3N (0.45 ml, 3.24 mmol) and diethyl phosphite (0.42 ml, 3.24 mmol). The reaction mixture was gradually warmed to room temperature and the mixture was stirred for 1 hr. The volatiles were removed under reduced pressure and the crude residue was washed with n-pentane to yield an yellow solid (2e) that was used in the next step without purification (0.42 g, 88%).
