실험 절차

To a stirred solution of 1-methoxy-5-methylisoquinolin-4-carbaldehyde (Intermediate-7) (2 g, 10 mmol) in ACN—H2O (120 mL, 1:1) was added, NaClO2 (5.4 g, 59.7 mmol), NaH2PO4 (5.5 g, 40 mmol) and the mixture was stirred at RT overnight. It was then extracted with EtOAc (3×150 mL), dried over Na2SO4, filtered and concentrated to give the desired acid derivative (1.2 g, 56%).
