Reaction Steps
A mixture of 380 mg (0.920 mmol) of N-[2-(3,4-dimethoxyphenyl)ethyl]-3-fluoromethoxy-2-(5,6,7,8-tetrahydronaphthalen-2-yl)acrylamide, 420 mg (1.01 mmol) of Lawesson's Reagent and 5 ml of anhydrous tetrahydrofuran was refluxed by heating for 3 hours. Water and ethyl acetate were added to the reaction mixture, and the ethyl acetate layer was washed with aqueous sodium hydroxide solution, aqueous ammonium chloride solution and saturated brine subsequently, dried over anhydrous magnesium sulfate and concentrated under reduced pressure. The residue was subjected to silica gel chromatography (eluent, hexane:ethyl acetate=3:1) to give 222 mg of N-[2-(3,4-dimethoxyphenyl)ethyl]-3-fluoromethoxy-2-(5,6,7,8-tetrahydronaphthalen-2-yl)acrylthioamide (the present compound 1160).
