Procedure

A mixture of 4′-[(4-{1-[4-(benzyloxy)phenyl]piperidin-4-yl}-5-oxo-7-propyl-4,5-dihydro[1,2,4]triazolo[1,5-a]pyrimidin-6-yl)methyl]biphenyl-2-carbonitrile (364 mg), 10% palladium-carbon (containing water by 50%, 91 mg), tetrahydrofuran (10 mL) and methanol (10 mL) was stirred at room temperature for 16 hr under a hydrogen atmosphere. The reaction mixture was filtered, and the solvent was evaporated. The residue was purified by preparative HPLC [eluent: 0.1% trifluoroacetic acid-containing acetonitrile/0.1% trifluoroacetic acid-containing water=5/95→100/0 (volume ratio)] to give the title compound as a colorless amorphous compound (183 mg, 59%).
