Reaction Steps

To a solution of the above nitrile (280 mg, 0.76 mmol) in THF at −78° C. was added freshly prepared LDA (0.32M, 2.6 mL, 0.83 mmol). The resulting mixture was stirred for 30 min. at −78° C. and 2-bromobenzyl bromide (570 mg, 2.28 mmol) in THF (1 mL) was added. The reaction was stirred for 3 hours at 0° C. and quenched with saturated aqueous NH4Cl (20 mL) to give 4-[2-(2-bromo-phenyl)-1-cyano-1-(4-trifluoromethyl-phenyl)-ethyl]-piperidine-1-carboxylic acid tert-butyl ester (264 mg, 65%) as a white foam after work-up and purification.
