실험 절차

A mixture of 4′-{[5-oxo-4-(4-oxocyclohexyl)-7-propyl-4,5-dihydro[1,2,4]triazolo[1,5-a]pyrimidin-6-yl]methyl}biphenyl-2-carbonitrile (12.67 g), 1-[1-(hydroxymethyl)cyclobutyl]ethanol (4.26 g), p-toluenesulfonic acid hydrate (0.57 g) and toluene (300 mL) was refluxed with heating for 5 hr while dehydrating with a Dean-Stark trap. The reaction mixture was cooled to room temperature, and diluted with ethyl acetate, and the mixture was washed with saturated aqueous sodium hydrogen carbonate solution and saturated brine, and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure, and the residue was purified by silica gel chromatography [eluent: hexane/ethyl acetate=80/20→40/60 (volume ratio)] to give the title compound as a colorless amorphous compound (13.64 g, 87%).
