실험 절차

Sodium hydride dispersion in oil (˜55%, 72 mg) was added in portions to a well stirred solution of N-(2-hydroxyethyl)propionamide (71 mg, 0.6 mmol) in THF (13 mL). After stirring the mixture for 15 min at RT [6-Chloro-5-(4-chloro-phenyl)-pyridin-3-yl]-((R)-4-isobutyl-2,2-dimethyl-oxazolidin-3-yl)-methanone (225 mg, 0.55 mmol) was added and stirring continued for 6 h at RT. The mixture was poured into water and extracted with diethyl ether. Organic phases were pooled, dried with Na2SO4 and the solvent was evaporated. The residue was purified by column chromatography on silica (cyclohexane/ethyl acetate 8:1) to yield 89 mg of the title compound as a white solid, MS (ISP) 488.2 (M+H)+.
