Reaction Steps

(3R,11aR)-1,2,3,4,11,11a-Hexahydro-2-benzyl-3-methyl-pyrazino[1,2-b]isoquinolin-6-one (81 mg, 0.26 mmol) and 10% palladium on carbon (25 mg) in methanol (6.5 ml) was stirred under a balloon of hydrogen for 19 h. Evapoaration of the filtrate after filtration through Celite® afforded pure (3R,11aR)-1,2,3,4,11,11a-hexahydro-3-methyl-pyrazino[1,2-b]isoquinolin-6-one (56 mg, 83% yield). MS (ESI) 217 (M+H).
