Reaction Steps

5-(4-Chloro-phenyl)-N-piperazin-1-yl-6-(2,2,2-trifluoro-ethoxy)-3-pyridinecarboxamide trifluoroacetate (1:1) (200 mg, 378 μmol, example 13b) was combined with acetonitrile (10 mL) to give a yellow solution. To this solution 2-bromoethyl acetate (760 mg, 500 μl, 4.55 mmol) and K2CO3 (157 mg, 1.13 mmol) were added successively. The reaction mixture was heated to 60° C., stirred for 20 h, filtered through a Celite® pad after cooling to ambient temperature and the filtrate was concentrated in vacuo. The residue was purified by flash chromatography (silica gel, 20 g, 0% to 50% methanol in ethyl acetate) to give the title compound (107 mg, 57%) as white solid; LC-MS (UV peak area/ESI) 97.8%, 501.1510 (M+H)+.
