Reaction Steps
Ammonium persulfate (231 g) was added to a solution of 2-methylpyridine (100 ml) in water-MeOH (350:700 ml); and then concentrated sulfuric acid (58 m,) was added. The mixture was stirred at reflux for 3 days. In this time other ammonium persulfate (20 g) and concentrated sulfuric acid (15 ml) were added. The mixture was quenched with NaOH 10% and extracted with EE (3×100 ml) and EA (3×100 ml), then the organic extracts were washed with brine (200 ml), dried and concentrated in vacuo to a yellow oil which was purified by flash chromatography (eluting with EE-EA 1:1) to give the title compound as a white solid (12.0 g).
