YieldReaction ConditionsOperation in experiment
79.5% Under a nitrogen atmosphere, compound 104(16.7 g, 100 mmol) was introduced into 25 mL of ethanol at 0~5 C followed by sodium ethanolate (6.8 g, 100 mmol). The yellow suspension was stirred for 20 minutes and compound 501 (12.2 g, 50 mmol) was added. The resulting mixture was stirred for 24 hours at room temperature and concentrated under reduced pressure. The residue was dissolved in ethyl acetate and washed with water and brine. The aqueous phase was extracted three times with ethyl acetate. The combined organic layers were dried over MgSO4 and evaporated to afford crude product 502 (12.1 g, 79.5%). LC-MS: 276(M+1), 1HNMR(DMSO-
