Reaction Steps

2-Benzyl-5-piperazin-1-yl-2H-isoquinolin-1-one (0.05 g, 0.16 mmol) from step 5 was added to a small (100 mL) Parr bottle, dissolved in 10 mL of EtOH, and a catalytic amount (25 mg) of palladium (10%) on charcoal was added (under N2 atmosphere). The vessel was then exposed to 60 psig hydrogen for 24 hours. Preparative HPLC gave the desired product, 2-benzyl-5-piperazin-1-yl-3,4-dihydro-2H-isoquinolin-1-one (8 mg, 0.025 mmol); M+H=322.
