A chilled solution of 4.0 g of 4-(2,3,4,5,6-pentafluorophenoxy)-4-phenylpiperidine and 2.4 ml of triethylamine in 50 ml of dichloromethane was treated with a solution of 1.4 ml of chloroacetyl chloride in 10 ml of dichloromethane and then stirred at ambient temperature for four hours. The mixture was diluted with 100 ml of ethyl acetate, dried over anhydrous magnesium sulfate, filtered and evaporated to yield 5.0 g of 1-(2-chloroacetyl)-4-(2,3,4,5,6-pentafluorophenoxy)-4-phenylpiperidine as an oil.
