実験手順

Solid 3'-cyanobiphenyl-4-ol (0.20 g, Example 36b)) was added to a suspension of sodium hydride (60%, 0.049 g) in dimethylformamide (5 ml) and the resulting solution stirred for 30 minutes. Solid (2R)-2-benzoyloxy-4-(3-pyridyl)-1-butyl para-toluenesulfonate (0.43 g) was then added and the mixture stirred at 60° C. for 2 hours. The mixture was cooled, poured into water (50 ml) and extracted with ethyl acetate. The combined organic extracts were dried over anhydrous magnesium sulfate, filtered and concentrated under reduced pressure. The residue obtained was purified by column chromatography over silica eluting with diethyl ether to give the sub-title compound as an oil (0.34 g).
