3-l3romo-pyridin-2-ol. A stirred suspension of 2-pyridone (77-0, 19 g, 200 mmol) in 200 mE of 1 M aqueous K13r at room temperature was treated over 15 mm with bromine (32 g, 200 mmol; CAUTION: Large quantities of 13r2 should be handled careffilly) in 200 mE of 1 M aqueous K13r, then stirred vigorously at room temperature 0/N. After 24 h, this solution deposited crystals which were filtered off and then recrystallized from acetonitrile to give 27.2 g (78%) of 3-bromo- pyridin-2-ol. (77-1) [J. Am. Chem. Soc. 1982, 104, 4142- 4146; Bioorg. Med. Chem. Lett. 2002, 12, 197-200; JMed Chem. 1979, 22, 1284-1290.] Molecular weight calcd. for C5H4I3rNO: 173; (M+H) found: 174
