실험 절차

2-Benzyl-5-nitro-2H-isoquinolin-1-one (1.0 g, 3.57 mmol) from step 3 was dissolved in 10 mL of EtOH, and a catalytic amount (50 mg) of 10% palladium on charcoal was added (under N2 atmosphere). The vessel was then closed and exposed to hydrogen at 1 atmosphere for 2 hours. TLC indicated that reduction of the nitro group was complete after 1 hour, and the mixture was filtered and concentrated in vacuo to give 5-amino-2-benzyl-2H-isoquinolin-1-one (0.687 g, 2.75 mmol) as a pale yellow solid.
