実験手順
A mixture of 2-(4-(4-acetylpiperazin-1-yl)phenyl)quinazolin-4(3H)-one (2.27 g, 6.5 mmol) and 2 N HCl (100 mL) were heated at 100° C. for 4 hours. Then, the mixture was cooled to room temperature, basified to pH 8 with 2 N NaOH, extracted with CH2Cl2 (3×150 mL), dried over anhydrous MgSO4, filtered, and concentrated to afford 2-(4-(piperazin-1-yl)phenyl)quinazolin-4(3H)-one as a pale yellow solid (1.8 g, 90%).
