실험 절차

Combine (S)-3-(3,4-dichlorophenyl)-3-(2-hydroxyethyl)pyrrolidine (R,R)-di-p-anisoyltartaric acid salt (6.0 g, 8.84 mmol) acetone (40 mL), water (40 mL), sodium hydroxide (0.335 g, 8.87 mmol), and sodium bicarbonate (3.73 g, 8.87 mmol). Cool to about 0° C. Add a solution of 3,4,5-trimethoxybenzoyl chloride (2,2 g, 9.7 mmol) in acetone (12 mL) over about 15 minutes. After 3 hours, partition the reaction mixture between ethyl acetate and brine. Extract the organic layer with 1 M sodium hydroxide solution, saturated sodium bicarbonate solution, 1 M hydrochloric acid solution, then brine. Dry the organic layer over MgSO4, filter, and evaporate in vacuo to give the title compound: Rf=0.11 (silica gel, ethyl acetate).
