YieldReaction ConditionsOperation in experiment
64.1% With sulfuric acid; at 0℃; for 21h;Reflux; To a solution of <strong>[38116-61-9]2-hydroxy-6-methylnicotinic acid</strong> (10.0 g, 0.0653 mole) in methanol (100 mL), sulfuric acid (3.5 mL) was added drop wise at 0 C and the mixture was stirred for 21 h under reflux. The reaction mixture was concentrated under reduced pressure, the residue was neutralized with saturated aqueous sodium bicarbonate solution under ice-cooling, and the mixture was extracted with 5 % methanol in chloroform (200 mL x 3). Organic layer was washed with brine solution (50 mL) and dried over Na2S04 and the solvent was concentrated under vacuum to afford the title compound. (0233) Yield: 7.0 g, 64.1%; 1H - NMR (DMSO- 6, 400 MHz) d ppm: 2.23 (s, 3H), 3.70 (s, 3H), 6.09 - 6.11 (d, J = 7.24 Hz, 1H), 7.98 - 8.00 (d, J = 7.36 Hz, 1H), 12.10 (s, 1H); Mass (m/z): 168.1 (M+H)+.

YieldReaction ConditionsOperation in experiment
100% In methanol; Step A Methyl-2-hydroxy-6-methylpyridine-3-carboxylate Acetyl chloride (50 ml) was added cautiously to a stirred suspension of <strong>[38116-61-9]2-hydroxy-6-methylpyridine-3-carboxylic acid</strong> (14.3 g, 93.44 mmol) in dry methanol (500 ml) and the resulting solution was heated to reflux. After 16 h the solution was evaporated in vacuo to give the title compound (15.62 g, 100%) as a solid: 1 H NMR (DMSO) shows the methyl singlet at delta 3.71.
