To 4-chloro-3-(4-cyano-6-trifluoromethyl-pyridin-3-yl)-N-(2-hydroxy-phenyl)-N-methyl-benzamide (50 mg, 0.12 mmol) dissolved in DMF (500 μL), methanesulfonic acid 2-(pyridin-2-yloxy)-ethyl ester (30 mg, 0.14 mmol) and K2CO3 (50 mg, 0.36 mmol) were added. The mixture was stirred at rt overnight then heated at 40° C. for 1 h. After filtration and dilution with MeOH the mixture was purified by prep HPLC yielding 4-chloro-3-(4-cyano-6-trifluoromethyl-pyridin-3-yl)-N-methyl-N-{2-[2-(pyridin-2-yloxy)-ethoxy]-phenyl}-benzamide 51-1. MS: 553.2 (M+H)+, tR=5.2 min (method 3).
