Procedure

To a solution of 5-bromo-4-methyl-3-(3-trifluoromethyl-phenyl)-pyridin-2-ylamine (Int. 1, 1.91 g, 5.77 mmol) in pyridine (25 mL) was added p-toluenesulfonyl chloride (1.75 g, 9.18 mmol) and then the reaction mixture was heated at 80° C. for 23 hrs. The solvent was removed by evaporation in vacuo and then the residue was purified by flash chromatography, eluting with a gradient of 0-30% EtOAc in cyclohexane, to give the title compound as an off-white solid (2.41 g).
