実験手順
Prepared according to the method described in Example 26e) from (2S)-2-(tert-butyldimethylsilyloxy)-4-(3-pyridyl)-1-butyl para-toluenesulfonate (0.46 g, Example 26d)), sodium hydride (60%, 0.056 g) and 4-(3-cyanophenyl)phenol (0.273 g) in dimethylformamide (5 ml). The adduct was dissolved in tetrahydrofuran (10 ml) and tetrabutylammonium fluoride (0.522 g) was added. The reaction was stirred at ambient temperature for 1 hour and was then poured into brine and extracted with ethyl acetate. The combined organic extracts were dried over anhydrous magnesium sulfate, filtered, concentrated under reduced pressure. The residue obtained was purified by column chromatography over silica eluting with ethyl acetate to give the title compound as a solid (0.22 g).
