PROCEDURE

实验过程

A mixture of 1-(3-hydroxybenzoyl)-2-(4,5-diphenyl-2-oxazolyl)piperidine (100 mg), ethyl bromoacetate (61 mg), and K2CO3 (84 mg) in acetonitrile (1.0 ml) was stirred at room temperature overnight and partitioned between water and ethyl acetate. The organic layer was separated, washed with water and brine, dried over MgSO4, and evaporated in vacuo. The residue was chromatographed over silica gel to afford 1-[3-(ethoxycarbonylmethoxy)benzoyl]-2-(4,5-diphenyl-2-oxazolyl)piperidine (90 mg) as a colorless oil.
