Participants

Reaction Steps

Prepared according to the method described in Example 26e) from (2R)-2-(tert-butyldimethylsilyloxy)-4-(3-pyridyl)-1-butyl para-toluenesulfonate (0.8 g), sodium hydride (60% dispersion in mineral oil, 0.10 g) and 2-chlorobiphenyl-4-ol (0.50 g) in dimethylformamide (15 ml). The adduct was dissolved in tetrahydrofuran (10 ml) and tetrabutylammonium fluoride (1.0 g) was added. The reaction was stirred at room temperature for 5 hours and was then poured into brine and extracted with ether. The combined organic extracts were dried over anhydrous magnesium sulfate, filtered and concentrated under reduced pressure. The residue was purified by reverse phase HPLC to give the title compound as a colourless gum (0.073 g).
