Procedure

To a stirred and cooled solution of 3-[6-methyl-4-(4-trifluoromethyl-phenyl)-[2,4′]bipyridinyl-2′-yl]-phenylamine (example 307) (0.200 g, 0.493 mmol) in EtOAc (2 mL) and sat. NaHCO3-sol. (1 mL) was added methanesulfonyl chloride (1.0 mL, 13.6 mmol) and the mixture was stirred at 23° C. for 2 h. Diluted with EtOAc, washed with sat. NaHCO3-sol. and water, dried the 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 to give the title compound as a white solid (0.070 g, 29%). MS (ISP) 484.4 [(M+H)+]; mp 196° C.
