Reaction Steps

To a mixture of 24.5 g of 4-hydroxy-4-[3-(trifluoromethyl)phenyl]piperidine (commercial) and 27.6 g of K2CO3 in 20 ml of DMF is added dropwise, at rt, 17.1 g of benzyl bromide, and the mixture is then heated at 40° C. for 2 hours and stirred overnight at rt. The reaction mixture is concentrated under vacuum, the residue is taken up in water and extracted with EtOAc, the organic phase is washed with water and dried over Na2SO4, and the solvent is evaporated off under vacuum. 31 g of the expected product are obtained.
