Water → N-[1-methyl-1-(3-chlorophenyl)ethyl]-N-(2-methyl-2-propenyl)-2-bromo-2-(2-fluorophenyl)acetamide

Participants

Reaction Steps

In 30 ml of dichloromethane containing 2.8 g of pyridine, 4.0 g of 2-bromo-2-(2-fluorophenyl)acetyl chloride were added dropwise to 2.5 g of N-[1-methyl-1-(3-chlorophenyl)ethyl]-2-methyl-2-propenylamine at 10° to 15° C. After stirring at room temperature for 1 hour, the solution was poured into water, and extraction was then made with dichloromethane. The resultant extract was washed with a saturated aqueous sodium bicarbonate solution, and dried over anhydrous sodium sulfate. After concentration, column chromatography was done to obtain 2.0 g of the desired N-[1-methyl-1-(3-chlorophenyl)ethyl]-N-(2-methyl-2-propenyl)-2-bromo-2-(2-fluorophenyl)acetamide.
