Methanesulfonyl chloride → 3-(4-(4-cyano-1-methyl-1H-benzo[d][1,2,3]triazol-6-yl)-2-(trifluoromethyl)phenoxy)propyl methanesulfonate

Participants

Reaction Steps

Methanesulphonyl chloride (6.29 g) was added dropwise to a solution of 6-(4-(3-hydroxypropoxy)-3-(trifluoromethyl)phenyl)-1-methyl-1H-[1,2,3]triazolo[4,5-c]-pyridine-4-carbonitrile (10.34 g) and diisopropylethylamine (22.7 ml) in DCM (300 ml) at 0° C. The mixture was stirred at room temperature for 2 hours. The DCM was removed under reduced pressure, MeOH and water were added to the residue and the solid was collected by filtration to give the expected product (11.56 g). 1H NMR (DMSO) δ: 8.96 (s, 1H), 8.49 (d, 1H), 8.46 (s, 1H), 7.51 (d, 1H), 4.46 (s, 3H), 4.39 (t, 2H), 4.34 (t, 2H), 3.18 (s, 3H), 2.21 (quin, 2H).
