PROCEDURE

实验过程

Combine 1-Cyclohexyl-3-(3,5-dichloro-4′-hydroxy-biphenyl-4-ylmethyl)-pyrrolidin-2-one (prep 55) (0.15 g, 0.36 mmol), ethyl 2-bromoisobutyrate (0.28 g, 1.43 mmol) and Cs2CO3 (0.35 g, 1.07 mmol) in DMF (7 mL) and heat to 60° C. for 16 hours. Cool the reaction, extract with diethyl ether and water, dry (Na2SO4) and then purify by normal phase chromatography (30 to 80% gradient of ethyl acetate in hexanes) to afford 200 mg (100%) of the title compound: LC-MS (ES +) m/z=exact mass calcd for C29H35Cl2NO4 531, found 532 and 534 (M+1 and M+3, 100%).
