Reaction Steps

A mixture of 3-amino-7,8-dimethoxy-2-(5-benzyloxy-2-methylphenyl)-2,5-dihydro-4H-pyrazolo[4,3-c]quinolin-4-one (50 mg), 10% palladium/active carbon (50% water, 25 mg), methanol (20 ml) and ethyl acetate (20 ml) was stirred under the hydrogen atmosphere for 1 day. The reaction mixture was filtered, and the filtrate was concentrated under reduced pressure. The residue was solidified by adding ethyl acetate-hexane. The solid was collected by filtration, washed with ethyl acetate-hexane, and then dried to obtain the target compound (25 mg).
