실험 절차
A solution of 350 mg (0.66 mmol) (R)-1-[[4-[2-[(R)-2-tert-butoxycarbonyl-pyrrolidin-1-yl]-2-oxo-ethoxy]-phenoxy]-acetyl]-pyrrolidine-2-carboxylic acid tert-butyl ester in 4 ml trifluoroacetic acid was stirred for 3 h at room temperature. The solvent was removed in vacuo and the residue suspended in 10 ml ether. The resulting suspension was stirred overnight. Filtration and drying gave 265 mg (96%) of the title compound as a white powder. MS m/e (%): 443 (M+Na+, 48), 438 (M+NH4+, 39), 421 (M+H+, 100).
