Reaction Steps
A solution of (1S,6R)-2,2-difluoro-6-{[(1R)-1-phenylethyl]amino}cyclohexanol 31 (2 g, 7.83 mmol) in methanol (100 mL) was degassed with nitrogen, treated with Pd(OH)2/C (0.55 g) and then placed under an atmosphere of hydrogen and stirred vigorously for 16 hours. The reaction was filtered, washing with methanol, and evaporated in vacuo to give 1.0 g (84%) of (1S,6R)-6-amino-2,2-difluorocyclohexanol 32 as a white solid: 1H NMR (500 MHz, CD3OD) δ 3.34 (1H, m), 2.74 (1H, m), 2.07 (1H, m), 1.89 (1H, m), 1.73 (2H, m), 1.50 (1H, m), 1.27 (1H, m).
