To a suspension of 5.0 g (35.9 mmol) of 2-hydroxy-nicotinic acid in 30 ml acetic acid was added dropwise 7.5 g (46.7 mmol) bromine. The mixture was maintained at 70-80° C. overnight. The mixture was cooled and the acetic acid was removed under reduced pressure. Water (100 ml) was added and the product was filtered and washed with water (3×100 ml). The solid was dried in a vacuum oven at 65° C. for 48 hours to provide 6.1 g (78% yield) of the title compound. MS: m/z (APCI, AP+) 219.0 [M.]+. CHN Analysis: Calcd: C, 33.06; H, 1.85; N, 6.42.
