A mixture of 4′-{[2-ethyl-1-(4-hydroxyphenyl)-6-oxo-4-propyl-1,6-dihydropyrimidin-5-yl]methyl}biphenyl-2-carbonitrile (600 mg), 4,4-difluorocyclohexanol (362 mg), diisopropyl azodicarboxylate (1.9 M in toluene, 1.4 mL), triphenylphosphine (698 mg) and tetrahydrofuran (10 ml) was stirred at 60° C. for 3 hr. The reaction mixture was diluted with ethyl acetate, and successively washed with water and saturated brine, dried over anhydrous magnesium sulfate and concentrated in vacuo. The residue was purified by column chromatography on silica gel to give the title compound as a pale yellow oil (635 mg, 86%).
