Stage #1: With sodium hydrogencarbonate In water; acetonitrile at 20℃;
Stage #2: With hydrogenchloride In water; acetonitrile
1- (((9H-Fluoren-9-yl)methoxy)carbonylamino)cyclopentanecarboxylic acid(compound 4 of example A): Fmoc-OSu (3.13 g, 9.3 mmol) was added to a solution of 1- aminocyclo- pentanecarboxylic acid (1.0 g, 7.8 mmol) and NaHC03 (1.63 g, 19.4 mmol) in acetonitrile/water (100 mL, 1 : 1). The reaction mixture was stirred at room temperature overnight. Most of the solvent was removed under reduced pressure and the resulting mixture was adjusted to pH = 2 with 2 N HCI and extracted with DCM. The combined extracts were washed with brine, dried over anhydrous Na2S04 and concentrated. The residue was purified by flash column chromatography on silica gel (PE/EA = 20: 1) to afford compound 4 of example A (0.75 g, 28percent yield) as a white solid.
