Temperature-78 °C

Reaction Steps

Treat a −78° C. solution of [4-(tert-butyl-diphenyl-silanyloxy)-cyclohexyl]-acetic acid ethyl ester (4.71 g, 11.49 mmol) in THF (40 mL) with a 1.6M solution of lithium diisopropylamide in THF (7.18 mL, 14.36 mmol) and stir at −78° C. for 20 minutes under N2. Treat the reaction with bromoacetonitrile (1.71 g, 14.36 mol) and stir at −78° C. for 2 hours. Warm the reaction to room temperature and stir for 2 hours. Quench the reaction with 1N HCl at 0° C. Dilute the reaction with ethyl acetate and wash with water. Dry the organic layer (Na2SO4), remove the solvent in vacuo to afford crude product, and purify with a 25% to 40% ethyl acetate in hexanes gradient to afford 2.62 g (50%) of the titled product. MS (m/z): 450 (M+1).
