Reaction Conditions

Reaction Steps

Two hundred milligrams (200 mg) of N-[2-(3,4-dimethoxyphenyl)ethyl]-3-hydroxy-2-(4-methylphenyl)acrylamide (0.586 mmol), 28 mg (0.70 mmol) of 60% sodium hydride, 2 ml of anhydrous N,N-dimethylformamide and 1 ml of anhydrous diethyl ether were mixed and 0.5 ml of bromofluoromethane was added thereto at −5° C. The mixture was stirred at −5° C. for 30 minutes and then stirred at 0° C. for 1 hour. The reaction mixture was added to water and extracted with ethyl acetate. The organic layer was washed with 5% hydrochloric acid, saturated aqueous sodium bicarbonate solution and saturated brine subsequently, dried over anhydrous magnesium sulfate and concentrated under reduced pressure. The residue was subjected to silica gel preparative thin layer chromatography (eluent, hexane:ethyl acetate=2:1) to give 205 mg of N-[2-(3,4-dimethoxyphenyl)ethyl]-3-fluoromethoxy-2-(4-methylphenyl)acrylamide (the present compound 1-4).
