To a stirred solution at room temperature of XI (210 mg, 0.62 mmol), 4′-morpholino acetophenone (227 mg, 1.11 mmol) or acetophenone derivative (1.5–2.0 equiv.) in MeOH (10 ml) was added a solution of NaOH (1.9 ml, 1N in H2O). A precipitate appeared. After 3 days, the reaction mixture was filtered off, rinsed with MeOH, air-dried and dried under vacuum to afford the title compound XXVf (295 mg, 0.56 mmol, 90% yield) as a yellow solid.
