実験手順

To a solution of (S)-3-((R)-6-(4-fluoro-3-methylbenzyloxy)-2-(4-fluoro-3-methylphenoxy)hexanoyl)-4-isopropyloxazolidin-2-one (100 mg, 0.20 mmol) dissolved in 2 mL of THF, methanol, and 50 wt % NH2OH in H2O (2:2:1) was added KCN (4.0 mg, 0.06 mmol). The resulting mixture stirred for 3 days at room temperature. The reaction was quenched by the addition of 1M aqueous HCl (10 mL) and the resulting mixture extracted with ethyl acetate (3×10 mL). The combined organic layers were washed with brine (2×5 mL). The product was isolated by flash column chromatography eluting with 0% to 10% methanol/DCM to give the title compound (54.2 mg) as colorless oil.
