실험 절차

In a manner similar to the method described in Example 13, rac-(2′S,3′S,4′S)-6-chloro-2′-(3-chloro-2-fluoro-phenyl)-4′-(2,2-dimethyl-propyl)-2-oxo-1,2-dihydro-spiro[indole-3,3′-pyrrolidine]-1′-carboxylic acid 4-methoxycarbonyl-phenyl ester (10 mg, 0.02 mmol) was heated with aqueous LiOH (4 mg, 0.2 mmol) in tetrahydrofuran (3 mL), water (3 mL), and methanol (1 mL) at room temperature for 18 h to give rac-(2′S,3′S,4′S)-6-chloro-2′-(3-chloro-2-fluoro-phenyl)-4′-(2,2-dimethyl-propyl)-2-oxo-1,2-dihydro-spiro[indole-3,3′-pyrrolidine]-1′-carboxylic acid 4-carboxy-phenyl ester as a white solid (Yield, 8 mg, 82%).
