Procedure
To a mixture of 4′-({5-oxo-7-propyl-4-[trans-4-(tetrahydro-2H-pyran-4-ylamino)cyclohexyl]-4,5-dihydro[1,2,4]triazolo[1,5-a]pyrimidin-6-yl}methyl)biphenyl-2-carbonitrile (0.33 g), sodium sulfate (1.5 g), aqueous formaldehyde solution (0.50 mL) and tetrahydrofuran (4 mL) was gradually added sodium triacetoxyborohydride (0.63 g) at room temperature, and the mixture was stirred at room temperature for 114 hr. 0.5M Aqueous sodium hydroxide solution was added, and the mixture was extracted with ethyl acetate. The organic layer was washed with saturated brine, and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure, and the residue was purified by silica gel column chromatography to give the title compound as a colorless solid (0.13 g, 39%).
