Procedure

Potassium t-butoxide (2.59 mmole, 2.6 ml of a 1.0M solution in THF) was cooled to −50° C. Acetonitrile (0.106 g, 2.59 mmole) was slowly added and stirred for 15 min. Benzaldehyde 143 (0.55 g, 2.16 mmole) in THF (1.0 ml) was added and the reaction was allowed to warm to 0° C. over 30 min. Sat. NH4Cl (20 ml) and EtOAc (30 ml) was added and stirred for 10 min. The organic layer was dried over Na2SO4 and evaporated giving 3-(3-((4,4-difluorocyclohexyl)methoxy)phenyl)-3-hydroxypropanenitrile (144) as an oil. Yield (0.622 g, 97%): 1H NMR (400 MHz, DMSO-d6) δ 7.22 (t, J=7.8 Hz, 1H), 6.96-6.93 (m, 2H), 6.82 (ddd, J=8.2, 2.6, 0.8 Hz, 1H), 5.89 (d, J=4.8 Hz, 2H), 4.85-4.81 (m, 1H), 2.86 (ABd, J=16.4, 5.0 Hz, 1H), 2.77 (ABd, J=16.8, 6.8 Hz, 1H), 2.04-1.96 (m, 2H), 1.88-1.73 (m, 5H), 1.35-1.25 (m, 2H).
