4-{4-[6-(6-Trifluoromethyl-pyridin-3-ylamino)-pyridin-3-yl]-phenyl}-piperidin-4-ol (153 mg, 0.37 mmol, prepared by analogous procedures described above) was dissolved in DMF (2 mL) and to it was added K2CO3 (128 mg, 0.93 mmol) followed by bromo-acetic acid ethyl ester (0.050 mL, 0.44 mmol) added dropwise, and the reaction was stirred for 18 hours. The reaction mixture was partitioned between 40% EtOAc/hexanes and water, washed with brine, dried with magnesium sulfate, filtered, and concentrated via rotary evaporation to obtain the title compound, as a crude oil, which was taken to the next step without purification: MS (M+H)+ 499.4.
