YieldReaction ConditionsOperation in experiment
31% With sodium nitrite; In sulfuric acid; water; a 3-Bromo-6-hydroxy-4-methyl pyridine Sodium nitrite (5.44 g, 78.8 mmol) in water (14 ml) was added dropwise to 2-amino-5-bromo-4-methylpyridine (12.83 g, 68.6 mmol) in sulphuric acid (20%) (69 ml) at 0-5 C. After 1 h at 0 C. the solution was heated to reflux for 1 h. The solution was basified to pH 10 with sodium hydroxide solution (40%) and cooled to 5 C. and the precipitated product separated by filtration. Recrystallisation from ethanol gave the title compound (5.97 g, 31%) as white needles (m.p.200-201 C.); δH (D6 -DMSO) 2.17 (3H, s, CH3), 6.40 (1H, s, 3-H), 7.76 (1H, s, 6-H), 11.58 (1H, s, NH): m/z (E.I.) 189 (M+, 100%), 187 (M+, 97%); (Found: M+, 186.9634. C6 H6 NOBr requires M, 186.9633).

YieldReaction ConditionsOperation in experiment
5-bromo-4-methylpyridin-2-amine (0.578 mmol) was dissolved in acetic anhydride (5.78 mmol) and heated at 1 10 C for 30 minutes. The reaction was quenched with ice. The aqueous reaction mixture neutralized with sodium hydroxide solution was extracted with ethyl acetate. The ethyl acetate layer was separated and dried over sodium sulfate. The organic layer was evaporated to dryness. The crude material was purified (silica column, MeOH/CHCL). 1HNMR (300MHz, DMSO-d6): 10.53 (s, 1H), 8.34 (s, 1H), 8.06 (s, 1H), 2.30 (s, 3H), 2.05 (s, 3H); MS (m/z): 231 (M+2)+.
