Procedure

A mixture of 4-benzyl-9-bromo-8-fluoro-2,3,4,5-tetrahydro-1,4-benzoxazepine (500 mg, 1.49 mmol), 3-furanboronic acid (250 mg, 2.23 mmol), potassium carbonate (206 mg, 1.49 mmol), tetrakis(triphenylphosphine)palladium(0) (172 mg, 0.149 mmol), 1,2-dimethoxyethane (5 ml) and water (0.5 ml) was stirred under an argon atmosphere at 100° C. for 3 hr. The reaction mixture was poured into water, and the mixture was extracted with ethyl acetate. The extract was washed with water and brine, and dried over anhydrous sodium sulfate. The solvent was evaporated under reduced pressure, and the residue was purified by silica gel column chromatography (hexane:ethyl acetate=1:1) and preparative HPLC to give the desired product (104 mg, 21.7%) as an oil.
