HCID 6422Trifluoroacetic acidSolvent

Procedure

A solution of 750 mg (1.41 mmol) (R)-1-[[3-[2-[(R)-2-tert-Butoxycarbonyl-pyrrolidin-1-yl]-2-oxo-ethoxy]-phenoxy]-acetyl]-pyrrolidine-2-carboxylic acid tert-butyl ester in 6 ml trifluoroacetic acid was stirred for 3 h at room temperature. The solvent was removed in vacuo and the residue suspended in 15 ml ether. The resulting suspension was stirred overnight. Filtration and drying gave 581 mg (98%) of the title compound as a white powder.
