Benzoyl chloride → HCID 12804759, compound

Participants

Reaction Steps

2.0 g of 1-methyl-4-(α-phenyl-2-tolyl)-4-piperidinol, Example 1, is treated with 10 ml of benzoyl chloride with stirring and cooling. The reaction solution is diluted with 20 ml of ether, stirred for two hours and the resulting precipitate collected by suction filtration. The filter cake is washed well with ether and dried in vacuo at 40° C. over sodium hydroxide pellets. The dried filter cake is recrystallized twice from a chloroform-ether mixture to give colorless crystals, mp 197°-198° C. of 4-benzoyloxy-1-methyl-4-(α-phenyl-2-tolyl)piperidine hydrochloride.
