Reaction Steps

To a solution of (S)-1-phenylethyl 3,3-difluorocyclopentanecarboxylate (diastereomer-1 or diastereomer-2, 0.15 g) in ethanol (5 mL) was added 10% Pd—C. The reaction mixture was stirred at rt under H2 for 16 h. The reaction mixture was filtered and the filtrate was concentrated to afford corresponding enantiomers of 3,3-difluorocyclopentanecarboxylic acid. 1H NMR (400 MHz, METHANOL-d4) ppm 2.97-3.08 (1H, m), 2.28-2.41 (2H, m), 1.93-2.23 (4H, m).
