Procedure

6-(4-((2-Methoxyethoxy)methoxy)-3-(trifluoromethyl)phenyl)-1-methyl-1H-[1,2,3]triazolo[4,5-c]pyridine-4-carbonitrile (6.31 mmol, 2.57 g) was dissolved in THF (42 ml) and hydrochloric acid (2M aq) (31.5 mmol, 15.77 ml) added. The mixture was heated to 65° C. for 4 hours, after which time LCMS indicated no reaction. THF (21 ml) was added and heating continued for 16 hours then EtOAc was added and the solution basified with aqueous ammonia. Organics were separated and solvent evaporated under reduced pressure. The resulting pale yellow solid was washed with EtOAc/ether (1:1) and dried to afford product 6-(4-hydroxy-3-(trifluoromethyl)-phenyl)-1-methyl-1H-[1,2,3]triazolo[4,5-c]pyridine-4-carbonitrile (82% yield). 1H NMR (DMSO) δ: 8.85 (s, 1H), 8.36 (s, 1H), 8.32 (d, 1H), 7.18 (d, 1H), 4.45 (s, 3H).
