Reaction Steps

To a mixed solution of 6-benzyloxycarbonylamino-3-tert-butoxycarbonylaminomethyl-2-isobutyl-4-phenyl-1(2H)-isoquinolinone (synthesized according to the method similar to that in Example 110 (1)) (0.45 g, 0.81 mmol) in tetrahydrofuran (20 ml) and ethanol (20 ml) was added 5% palladium-carbon (0.1 g). The obtained mixture was hydrogenated, at ambient temperature and atmospheric pressure. The catalyst was filtered off and the filtrate was concentrated under reduced pressure. The precipitated crystals were collected by filtration to give 6-amino-3-tert-butoxycarbonylaminomethyl-2isobutyl-4-phenyl-1(2H)-isoquinolinone (0.31 g, 87.0%) as crystals.
