실험 절차

Methanesulfonyl chloride (3.65 ml) was added to a methylene chloride (50 ml) solution containing N-formylpiperazine (5.08 g) and triethylamine (6.85 ml) under ice-cooling, and the mixture was stirred at room temperature for 18 hours to undergo reaction, thereby obtaining 1-formyl-4-methanesulfonylpiperazine. This compound was acid-treated with hydrochloric acid to obtain 1-methanesulfonylpiperazine.hydrochloride. Also, 1-(phenylsulfonyl)piperazine.hydrochloride was obtained in the same manner as mentioned above by using the corresponding starting material.
