Procedure

The title compound was prepared from 3-[6′-methyl-4′-(4-trifluoromethyl-phenyl)-[2,2′]bipyridinyl-6-yl]-benzenesulfonyl chloride (example 1.2) (0.275 g, 0.5 mmol) by treatment with excess ethanolamine in THF (5 mL) at 23° C. for 16 h. Diluted with EtOAc, washed with 1 N HCl, dried organic layer over Na2SO4. Removal of the solvent in vacuum left a crude product, which was purified by silica gel column chromatography with n-heptane/EtOAc followed by trituration with n-heptane/diethyl ether to give the title compound (0.110 g, 43%) as a white solid. MS (ISP) 513.9 [(M+H)+]; mp 110° C. (dec.).
