Procedure

A mixture of 4′-{[2-ethyl-1-(4-hydroxyphenyl)-6-oxo-4-propyl-1,6-dihydropyrimidin-5-yl]methyl}biphenyl-2-carbonitrile (4.0 g), 1,4-dioxaspiro[4.5]decan-8-ol (2.82 g), diisopropyl azodicarboxylate (1.9 M in toluene, 3.2 mL), triphenylphosphine (4.67 g) and tetrahydrofuran (20 ml) was stirred at room temperature for 2 hr. The reaction mixture was diluted with ethyl acetate, 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 amorphous solid (5.13 g, 98%).
