実験手順
8-Benzyloxy-2-p-chlorophenyl-8-methy-2,3,6,7,8,9-hexahydropyrazolo[4,3-c]quinolin-3(5H)-one (4 g) is dissolved in 200 mL of a 1:1 mixture of DMF/EtOH and subjected to catalytic hydrogenation with 5% palladiium on carbon (1 g) for 24 hours under 1 atm. of hydrogen. After the reaction is over, the catalyst is filtered off, the filtrate is evaporated, and the dried residue is triturated with EtOH to yield 2-p-chlorophenyl-8-hydroxy-8-methyl-2,3,6,7,8,9-hexahydropyrazolo[4,3-c]quinolin-3(5H)-one.
