실험 절차

Methanesulfonic acid 4-(4-methanesulfonylpiperazin-1-yl)phenyl ester (3.2 g, 9.5 mmol) is placed in 29 ml of a 1N aqueous solution of sodium hydroxide. The reaction medium is stirred at reflux for 48 h. Acetic acid is added at ambient temperature to pH 4. The precipitate formed is filter-dried and washed with water and then dried over P2O5. 2.6 g of expected 4-(4-methanesulfonylpiperazin-1-yl)phenol are obtained.
