Reaction Steps

A suspension of 7-nitro-3,4-dihydro-2H-isoquinolin-1-one (11.6 g, 60 mmol) and 10% Pd/C (1.2 g,) in MeOH was stirred overnight at RT under H2 (40 psi). The mixture was filtered through Celite® and washed with MeOH. The filtrate was evaporated under vacuum to afford 8.2 g of 7-amino-3,4-dihydro-2H-isoquinolin-1-one, which was used without further purification.
