Hydrochloric Acid → 4-Bromo-6-methylpyridin-3-ol

Participants

Reaction Steps

920 mg (3.05 mmol) 4-bromo-5-methoxymethoxy-2-methyl-pyridine (Stage 40.5) were dissolved in 5 mL MeOH, HCl conc. (1 mL, 12 mmol) was added and the reaction mixture was stirred for 2 h at rt. While concentrating the mixture in vacuo, the title compound (as hydrochloride) crystallized. Filtration afforded 570 mg white crystals. 1H-NMR (d6-DMSO, 400 MHz): 8.19 (s, 1H), 8.04 (s, 1H), 2.53 (s, 3H).
