Procedure

To 20 ml of dichloromethane were added 3.0 g of N-[1-methyl-1-(3,4-dichlorophenyl)ethyl]-N-(1-methyl-2-oxopropyl)amine and 3.5 g of pyridine, and 4.0 g of 2-fluorophenylacetyl chloride was then added dropwise thereto at 5° to 10° C. After stirring at room temperature for 1 hour, a saturated aqueous sodium hydrogencarbonate solution was added, followed by extraction with dichloromethane. After dried over anhydrous sodium sulfate, the solution was concentrated by an evaporator, and the resulting oil was dissolved in 20 ml of ethyl acetate. Next, 10 ml of a 28% methanol solution of sodium methylate was added thereto, and after stirring under reflux for 15 minutes, the temperature of the solution was returned to room temperature and water was then added, followed by extraction with ethyl acetate. Afterward, the solution was washed with a 12% hydrochloric acid and a saturated aqueous solution of sodium hydrogencarbonate, and then dried over anhydrous sodium sulfate. Next, the solution was concentrated by an evaporator, and then subjected to silica gel chromatography to obtain 2.5 g of 1-[1-methyl-1-(3,4-dichlorophenyl)ethyl]-4,5-dimethyl-3-(2-fluorophenyl)-3-pyrroline-2-one.
