実験手順

2-(6-Methoxy-pyridin-2-yl)-2-methyl-propionic acid ethyl ester (5.33 g) was dissolved in methanol (200 ml), added with 5 N aqueous solution of potassium hydroxide (25 ml), and then stirred under reflux. The reaction mixture was concentrated and neutralized with 2 N hydrochloric acid. The precipitated matters were collected by filtration and dried to obtain the title compound (3.55 g).
