Reaction Steps

Potassium carbonate (348 mg, 2.52 mmol) and benzofuran-7-ol (169 mg, 1.26 mmol) were successively added to a solution of 1-benzhydrylazetidin-3-yl methanesulfonate (400 mg, 1.26 mmol) in DMF (8 mL). The reaction mixture was stirred overnight at 90° C. and then diluted by addition of ethyl acetate (20 mL) and water (20 mL). The aqueous phase was separated and extracted with ethyl acetate (4×50 mL). The combined organic phases were washed with a saturated solution of sodium chloride (5×50 mL), dried over sodium sulfate, filtered and concentrated to dryness. The residue was purified by chromatography on silica gel using petroleum ether/dichloromethane (1:0 to 2:8 to 0:1) as eluent. The title product was obtained as a yellow oil (350 mg, 69%).
