Reaction Steps
Pyridinium chloride (293 mg) was added to 1-butyl-5,6-dimethyl-3-methoxy-2-pyridone (1-004-07) (124 mg), and the reaction mixture was heated with stirring in an oil bath at 200° C. under nitrogen atmosphere. After 30 min, the reaction mixture was dissolved in diethyl ether and water, extracted twice with diethyl ether, washed once with water, and dried over magnesium sulfate. The solvent was evaporated under reduced pressure to give 1-butyl-5,6-dimethyl-3-hydroxy-2-pyridone (1-004-08) (94 mg, 81%, m.p.: 112-116° C.)
