Reaction Steps

The title compound was prepared from 3-[6′-methyl-4′-(4-trifluoromethyl-phenyl)-[2,2′]bipyridinyl-6-yl]-benzenesulfonyl chloride (example I.2) (0.210 g, 0.429 mmol) by treatment with excess diethanolamine in THF (5 mL) at 23° C. for 16 h. Diluted with EtOAc, washed with 5% citric acid, sat. NaHCO3-sol. and brine, dried organic layer over Na2SO4. Removal of the solvent in vacuum left a crude product, which was purified by silica gel column chromatography with EtOAc followed by trituration with n-heptane/diethyl ether to give the title compound (0.120 g, 50%) as a white solid. MS (ISP) 557.6 [(M+H)+]; mp 176° C.
