실험 절차

To 4-(5-methyl-1-oxo-1,2-dihydro-isoquinolin-3-yl)-benzonitrile (100 mg, 0.38 mmol) was added 2M NaOH (1.5 mL) and the reaction mixture irradiated using a microwave (300 W, 130° C., 20 min). The reaction mixtures was diluted with water and adjusted to pH2 with 2M HCl whereupon a pale yellow solid precipitated out of solution. The solid was filtered, washed with water and dried. The solid was dissolved in DMF and passed through a Si-thiol cartridge to remove any residual palladium, eluting with DMF. The eluent was removed in vacuo to give 4-(5-methyl-1-oxo-1,2-dihydro-isoquinolin-3-yl)-benzoic acid as a pale yellow solid (120 mg, 63%).
