Reaktionsschritte

Acetic acid 2-methyl-6-[1,2,4]triazol-1-yl-pyridin-3-yl ester (125 mg, 0.57 mmol) was added to 2 M aqueous sodium hydroxide solution (1.6 mL) at 0° C. to give a slurry, and the mixture was stirred at 0° C. for 20 min and then at room temperature for 3 h. 2 M Aqueous hydrochloric acid was added to bring the pH to 6, and the mixture was extracted four times with ethyl acetate. The organic layers were combined and the solvent was evaporated to dryness to give 2-methyl-6-[1,2,4]triazol-1-yl-pyridin-3-ol (96 mg, 95%) as a white powder. 1H NMR (300 MHz, DMSO-d6) δ 2.36 (s, 3H), 7.33 (d, 1H, J=8.7 Hz), 7.51 (d, 1H, J=8.5 Hz), 8.18 (s, 1H), 9.12 (s, 1H), 10.19 (br s, 1H).
