Hydrochloric Acid → HCID 53657126, compound

Participants

Reaction Steps

60 ml of 5 N hydrochloric acid was added to a solution of 5.8 g of 4-{N-methyl-N-[2-(4-methylthiophenyl)ethyl]amino}-1-benzoylpiperidine in 20 ml of ethanol. The mixture was refluxed by heating, for 12 hours. To the reaction mixture was added 100 ml of ethanol, followed by concentration under reduced pressure. To the residue was added ice water. The mixture was made basic with a 25% aqueous sodium hydroxide solution and then extracted with chloroform. The extract was water-washed, dried with anhydrous sodium sulfate, and concentrated under reduced pressure to obtain 3.7 g of 4-{N-methyl-N-[2-(4-methylthiophenyl)ethyl]amino}piperidine as a light yellow oily substance.
