Reaction Steps
5,6-Dimethyl-2-methoxy-3-nitropyridine (1-013-06) (2.56 g) was dissolved in tetrahydrofuran (41 mL), and to the reaction mixture was added a suspension of 5% palladium on carbon (450 mg) in methanol (41 mL), and then the catalytic reduction was carried out. After 3 h, catalyst was filtered off, and the filtrate was evaporated under reduced pressure to give 3-amino-5,6-dimethyl-2-methoxypyridine (1-013-07) (2.096 g, 97.9%, m.p.: 56-58° C.) as a blackish brown crystal.
