To a solution of (4-((6-(1H-tetrazol-1-yl)pyridin-3-yloxy)methyl)-1H-1,2,3-triazol-1-yl)methyl pivalate (10 g, 27.9 mmol) in MeOH (60 mL) and THF (6 mL) was added sodium hydroxide (61.5 mL of a 1M solution in water). The mixture was stirred for 30 minutes and hydrochloric acid was added (61.5 mL of a 1M solution in water). The resulting solution was extracted with ethyl acetate, separated, dried over sodium sulfate, filtered and concentrated in vacuo to afford the expected product which was used in subsequent steps without further purification. 1H NMR (DMSO-d6): δ 10.07 (1H, s), 8.43-8.41 (2H, m), 8.00 (1H, d, J=8.8 Hz), 7.88 (1H, dd, J=3.2, 8.8 Hz), 6.32 (2H, s), 5.38 (2H, s), 1.08 (9H, s).
