Reaction Steps

137a (1.332 g, 4.891 mmol) was dissolved in a 1:1 mixture of methanol and ethyl acetate (30 mL). Palladium on charcoal (10%, 200 mg, 0.188 mmol) was added, and the mixture was stirred 2 h under hydrogen atmosphere (40 psi). The reaction mixture was filtered over Celite® and concentrated to afford 1.16 g (98% yield, 100% pure) of 4-(2-tert-butylphenoxy)pyridin-3-amine (137b) as a white solid.
