Acetyl chloride → 1-Acetyl-4-(3-trifluoromethylbenzoyl)-piperidine

Participants

Reaction Steps

To a solution of 32.1 g (0.125 mole) of 4-(m-trifluoromethylbenzoyl)piperidine in 75 ml of benzene and 21.2 g (0.2 mole) of Na2CO3, was added dropwise a solution of ten g (0.127 mole) of acetyl chloride in 75 ml of benzene. The mixture was refluxed for 2 hours. The mixture was filtered and the filtrate was concentrated under vacuum giving crude 1-acetyl-4-(m-trifluoromethylbenzoyl)piperidine. Yield 37.3 grams.
