실험 절차

A solution of chiral methyl 5-((2R,3S,4R,5S)-3-(3-chloro-2-fluorophenyl)-4-(4-chloro-2-fluorophenyl)-4-cyano-5-neopentylpyrrolidine-2-carboxamido)benzo[d]oxazole-2-carboxylate (64.5 mg, 0.101 mμmol) in THF (5 ml) was reacted with LITHIUM HYDROXIDE MONOHYDRATE (17.1 mg, 0.407 mmol) in water (2.5 ml) and stirred at rt for 4.5 hrs. The reaction mixture was treated with 1 N HCl (pH 5-6) and extracted with ethyl acetate. The organic extracts were washed with water, brine, dried with sodium sulfate, filtered and purified by silica gel chromatography with methylene chloride and methanol to give chiral-5-((2R,3S,4R,5S)-3-(3-chloro-2-fluorophenyl)-4-(4-chloro-2-fluorophenyl)-4-cyano-5-neopentylpyrrolidine-2-carboxamido)benzo[d]oxazole-2-carboxylic acid (7.8 mg., 12.4%) a white lyophilized solid. MS (ES+) m/z Calcd: [(M+H)+]: 627.13. found: 627.2. and chiral (2R,3S,4R,5S)—N-(benzo[d]oxazol-5-yl)-3-(3-chloro-2-fluorophenyl)-4-(4-chloro-2-fluorophenyl)-4-cyano-5-neopentylpyrrolidine-2-carboxamide (38.3 mg., 65.3%) as a white lyophilized solid. MS (ES+) m/z Calcd: [(M+H)+]: 583.14. found: 583.2.
