반응 단계

To a solution of Compound 1 (16.41 g, 64.9 mmol) in tetrahydrofuran (75 mL) at 0° C. was added dropwise a 1M solution of diisobutylaluminum hydride in toluene (97.3 mL). After 1 hr, the reaction was quenched with aqueous potassium sodium tartrate and diluted with ethyl acetate followed by warming to room temperature. After stirring for an additional hour, the layers were separated and the aqueous phase was re-extracted with ethyl acetate (2×). The extracts were combined, washed with brine, dried over anh. magnesium sulfate, filtered and concentrated in vacuo. Chromatography of the residue on silica gel (elution with ethyl acetate) provided 12.96 g of Compound 2 as an oil which crystallized upon standing.
