Reaction Steps

To 1-methyl-6-(4-(2-(piperidin-4-yl)ethoxy)-3-(trifluoromethyl)phenyl)-1H-[1,2,3]triazolo[4,5-c]pyridine-4-carbonitrile TFA salt (150 mg) in methanol (2 ml) was added 2-chloro-N,N-dimethylacetamide (67 mg) and DIPEA (0.23 ml). The mixture was heated at 90° C. for 40 minutes, then purified by basic HPLC to give 6-(4-(2-(1-(2-dimethylamino-2-oxoethyl)piperidin-4-yl)ethoxy)-3-(trifluoromethyl)phenyl)-1-methyl-1H-[1,2,3]triazolo[4,5-c]pyridine-4-carbonitrile which was then converted to HCl salt by lypholising with 1M hydrochloric acid (1 ml) (130 mg).
