Participants

Reaction Steps

To a solution of 57.5 g of 4-(2-fluorobenzoyl)-1-methyl piperidine and 68.7 g of potassium carbonate in 750 ml of toluene was added with stirring 47 g of phenylchloroformate. The reaction mixture was heated under reflux for 5 hrs, cooled to room temperature, filtered, and the solvent removed under reduced pressure to give an oil. Trituration of the oil with hexane gave 48.6 g (46%) of product. Recrystallization of 1.0 g of product from ethanol-water (2×) and from ethanol gave the analytical sample, mp 95°-96° C.
