2,3-Dichloro-5-hydroxypyridine Use and Manufacturing
A solution of KOH (728 mg, 13 mmol) in 7 ml of water was added to a solution of compound 3 (1 g, 4.8 mmol) in 10 ml of THF at 0 °C. After addition, the mixture was stirred at ambient temperature for 2 h. Then the mixture added dilute hydrochloric acid to adjust the pH value to weak alkaline and filtered. The filter residue was purified by recrystallization to give compound 4(517 mg, y: 65percent). H NMR (400 MHz, DMSO-d6) 5(ppm): 7.47(d, 1 H), 7.93(d, 1 H), 10.72(s, 1 H).Acetic acid 5, 6-dichloro-pyridin-3-yl ester (7.00 g, 34.0 mmol, 1.0 equiv.) was added to KOH (5.70 g) in H
