Reaction Steps

To the obtained (−)-3-(1-benzylpyrrolidin-3-yl)-5-methyl-2H-isoquinolin-1-one (27.5 g) were added 50% aqueous 10% palladium-carbon (6 g) and ethanol (400 ml), and the mixture was stirred under a hydrogen atmosphere at 50° C. for 6 hr. After celite filtration, the filtrate was concentrated and ethyl acetate was added to the obtained residue. The precipitated crystals were collected by filtration to give (−)-3-(pyrrolidin-3-yl)-5-methyl-2H-isoquinolin-1-one (16.8697 g).
