After absorption of hydrogen ceased, the mixture is filtered and the filtrate is concentrated under reduced pressure. The residue is dissolved in ethyl acetate and washed with water, dried over anhydrous magnesium sulfate and then concentrated to give 2.24 g of 4-[2-(6-methyl-2-pyridyl)ethoxy]aniline as yellowish brown powder.
