Procedure

A mixture of 3′-fluoro-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 (23 g), 1-[1-(hydroxymethyl)cyclobutyl]ethanol (7.6 g), 4-methylbenzenesulfonic acid (0.093 g) and toluene (200 mL) was heated with a Dean-Stark apparatus under reflux for 2 hr. The reaction mixture was concentrated under reduced pressure, and the residue was purified by silica gel column chromatography to give the title compound as a colorless solid (26 g, 90%).
