2-Hydroxy-3-methylpyridine Use and Manufacturing
General procedure: In a dry Schlenk tube 2-bromo-6-methylpyridine (5.98 g, 35.0 mmol) was dissolved in 100 mL oft-AmylOH and KOt-Bu (39.3 g , 350.0 mmol) was added. The mixture was stirred at 100 °C for 40 h. The solvent was removed under reduced pressure and the residue was dissolved in 50 mL of HCOWas added to the reactorPyridine-2-one 19-1 (0.095 g, 1 mmol)Dicumyl peroxide (0.81 g, 3 mmol) and 2 ml of acetic acid, 120 ° C reaction, TLC followed the reaction until complete.The crude product obtained after the completion of the reaction was purified by column chromatography (petroleum ether: ethyl acetate = 1: 1)Separation and purification to give the target product 19-2 (yield 85percent).Diisopropyl azodicarboxylate (1.02 g, 5.04 mmol) was added slowly to a solution of
