Procedure

Methanesulphonyl chloride (2.65 g) was added dropwise to a solution of 6-[4-(3-hydroxypropoxy)-3-(trifluoromethyl)-phenyl]-1-methyl-1H-imidazo[4,5-c]pyridine-4-carbonitrile (6.7 g) and diisopropylethylamine (9.7 ml) in NMP (40 ml). The mixture was stirred at room temperature for 3 hours. After adding ice (100 g), solid product was collected by filtration, washed with cold ethanol (20 ml) to give 3-[4-(4-cyano-1-methyl-1H-imidazo[4,5-c]pyridin-6-yl)-2-(trifluoromethyl)phenoxy]propyl methane-sulfonate (7.4 g). 1H NMR (DMSO) δ: 8.69 (s, 1H), 8.62 (s, 1H), 8.45 (d, 1H), 8.41 (s, 1H), 7.47 (d, 1H), 4.40 (t, 1H), 4.32 (t, 2H), 3.99 (s, 3H), 3.18 (s, 3H), 2.21 (tt, 2H).
