Reaction Steps

To a solution of 1-iodo-4-(trifluoromethyl)benzene (0.92 g, 3.4 mmol) in dry THF at −78° C. was added n-BuLi (3 mL, 1.6 M in hexane) dropwise and the mixture was stirred at the same temperature for 30 min. To this was added a solution of tert-butyl 4-benzoylpiperidine-1-carboxylate (1.0 g, 3.4 mmol) in minimum amount of dry THF dropwise and the resulting reaction mixture was allowed to warm up to rt over 2 h. The reaction was quenched with ammonium chloride solution, extracted with ethyl acetate, dried over anhydrous sodium sulfate and concentrated to afford tert-butyl 4-(hydroxy(phenyl)(4-(trifluoromethyl)phenyl)methyl)-piperidine-1-carboxylate (1.0 g, 66% yield) as a pale yellow solid which was used in the next step without further purification.
