실험 절차

A solution of 50 mg 2-{[1-(5,6-dichloro-pyridin-3-ylmethoxy)-naphthalene-2-carbonyl]-amino}-2-methyl-propionic acid methyl ester and 30 mg sodium ethoxide in 3 ml EtOH containing 5% of water was heated to 120° C. for 2 min using a microwave reactor. The reaction mixture was acidified to pH 4 with 2 M HCl and the precipitated solid was collected by filtration and purified by RP-HPLC to yield 40 mg 2-{[1-(5-chloro-6-ethoxy-pyridin-3-ylmethoxy)-naphthalene-2-carbonyl]-amino}-2-methyl-propionic acid.
