Reaction Steps

A mixture of acetic acid 6-chloro-2-methyl-pyridin-3-yl ester (316 mg, 1.7 mmol) and 15% aqueous sodium hydroxide (2.5 mL) was stirred at 0° C. for 15 min and then at room temperature for 1 h. 1 M HCl (12 mL) was added and the mixture was extracted 4 times with ethyl acetate. The ethyl acetate was evaporated to give 6-chloro-2-methyl-pyridin-3-ol (235 mg, 96%) as a white powder. 1H NMR (300 MHz, DMSO-d6) δ 2.26 (s, 3H), 7.09 (d, 1H, J=8.4 Hz), 7.14 (d, 1H, J=8.4 Hz), 10.08 (br s, 1H).
