実験手順

A mixture of 16.25 parts of 9-[(4-fluorophenyl)methyl]-8-[[1-(phenylmethyl)-4-piperidinyl]oxy]-9H-purine and 200 parts of methanol was hydrogenated at normal pressure and at 50° C. with 3 parts of palladium-on-charcoal catalyst 10% and 6 parts of Raney-nickel catalyst. After the calculated amount of hydrogen was taken up, the catalyst was filtered off and the filtrate was evaporated. The residue was taken up in trichloromethane and water was added. The product was extracted with trichloromethane. The extract was washed with water, dried, filtered and evaporated. The residue was stirred in 1,1'-oxybisethane. The precipitated product was filtered off and dried, yielding 10.5 parts (82.2%) of 9-[(4-fluorophenyl)methyl]-8-(4-piperidinyloxy)-9H-purine; mp. 79.3° C. (compound 56).
