Procedure

The title compound was prepared from 3-[6′-methyl-4′-(4-trifluoromethyl-phenyl)-[2,2′]bipyridinyl-6-yl]-benzenesulfonyl chloride (example I.2) (0.465 g, 0.951 mmol) by treatment with commercially available ethylamine (2 M in THF, 2.38 ml, 4.76 mmol) and triethylamine (1.33 ml, 9.51 mmol) 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 diethyl ether/heptane to give the title compound (0.260 g, 55%) as an off-white solid. MS (ISP) 498.3 [(M+H)+]; mp 135° C.
