Procedure

Methanesulphonyl chloride (0.23 ml) was added dropwise to a solution of 6-(4-(2-hydroxyethoxy)-3-(trifluoromethyl)-phenyl)-1-methyl-1H-imidazo[4,5-c]pyridine-4-carbonitrile (0.77 g) and diisopropylethylamine (1.2 ml) in NMP (6 ml). The mixture was stirred at room temperature for 3 hours. After adding cold water (20 ml), solid product was collected by filtration, washed with cold ethanol (20 ml) to give 2-(4-(4-cyano-1-methyl-1H-imidazo[4,5-c]pyridin-6-yl)-2-(trifluoromethyl)phenoxy)ethyl methanesulfonate (0.89 g).
