실험 절차

To a solution of rac-4-{2-[(2S,3R,4S)-4-(3-chloro-2-fluoro-phenyl)-3-(4-chloro-2-fluoro-phenyl)-3-cyano-2-(2,2-dimethyl-propyl)-pyrrolidin-1-yl]-acetylamino}-benzoic acid methyl ester (0.35 g, 0.57 mmol) in tetrahydrofuran (30 mL) was added an aqueous solution (1 N) of NaOH (10 mL, 10 mmol) and methanol (10 mL). The reaction mixture was stirred at room temperature for 24 h, and the “pH” of the solution was adjusted to 5-6 by aqueous HCl solution. The mixture was extracted ethyl acetate twice. The combined organic extracts were washed with water, brine, dried over MgSO4, and concentrated to give rac-4-{2-[(2S,3R,4S)-4-(3-chloro-2-fluoro-phenyl)-3-(4-chloro-2-fluoro-phenyl)-3-cyano-2-(2,2-dimethyl-propyl)-pyrrolidin-1-yl]-acetylamino}-benzoic acid as a white solid (0.33 g, 96%). HRMS (ES+) m/z Calcd for C31H29Cl2F2N3O3+H [(M+H): 600.1267; Found: 600.1628.
