実験手順

120 mg (0.353 mmol) of 3-acetyl-3-(3-chlorophenyl)-N-(3-phenyl-2-propene-1-yl)acrylamide was dissolved in 10 ml of DMF. 78.6 mg (0.283 mmol) of methylisothiourea monosulfate and 34.7 mg (0.424 mmol) of sodium acetate were added to the obtained solution at room temperature, and they were stirred at that temperature overnight. DMF was evaporated under reduced pressure. The residue was diluted with ethyl acetate and washed with saturated aqueous sodium chloride solution. The organic layer was dried over anhydrous magnesium sulfate and then concentrated under reduced pressure. 2-propanol was added to the residue, and they were heated to 120° C. and stirred overnight. The residue was purified by the silica gel chromatography (hexane/ethyl acetate=5/1) to obtain the title compound.
