Procedure

To a solution of tert-butyl 4-(2-(5-(4-cyano-1-methyl-1H-[1,2,3]triazolo[4,5-c]pyridin-6-yl)-3-(trifluoromethyl)pyridin-2-yloxy)ethyl)piperidine-1-carboxylate (1.15 g) in dichloromethane (10 ml) and acetonitrile (5 ml), trifluoroacetic acid (2 ml) was added and the mixture stirred at 20° C. for 1 h then solvent evaporated under reduced pressure. The resulting residue was dissolved in ethyl acetate (10 ml) and diethyl ether added dropwise until the mixture turned cloudy. The solution was allowed to stand for two hours. The desired product was collected by filtration and washed with ether, dried in vacuum oven to give 920 mg 1-methyl-6-(6-(2-(piperidin-4-yl)ethoxy)-5-(trifluoromethyl)pyridin-3-yl)-1H-[1,2,3]triazolo[4,5-c]pyridine-4-carbonitrile trifluoroacetate (78%).
