2-Methyl-5-(2-methyl-4-nitrophenoxy)pyridine → 3-Methyl-4-((6-methylpyridin-3-yl)oxy)aniline

Participants

Reaction Steps

A mixture of 2-methyl-5-(2-methyl-4-nitrophenoxy)pyridine (141 g, 0.58 mol) and 10% palladium on charcoal (13 g) in ethyl acetate (200 ml) and ethanol (700 ml) was stirred under an atmosphere of hydrogen (1.2 bar) for 5 hours. After reaction completion, the mixture was purged with nitrogen and the catalyst was filtered off. The filtrate was evaporated to dryness to give 3-methyl-4-[(6-methylpyridin-3-yl)oxy]aniline (120.6 g, 98%) as a white solid; Mass spectrum MH+ 215.
