690 mg of 4-[(3-chloro-4-methoxybenzyl)amino]-1-[2-(1-hydroxycyclopentyl)-1-ethynyl]-6-phthalazine carbonitrile was dissolved in 200 ml tetrahydrofuran, 50 mg of 10% Pd—C was added thereto, and the mixture was stirred for 0.5 hr in a hydrogen atmosphere. The reaction solution was filtered through Celite, and the filtrate was evaporated. The resulting residue was purified by silica gel column chromatography to give 400 mg of 4-[(3-chloro-4-methoxybenzyl)amino]-1-[2-(1-hydroxycyclopentyl)ethyl]-6-phthalazine carbonitrile. This product was converted in a usual manner into the hydrochloride.
