실험 절차
To a solution of 0.30 g of 1-(6-chloro-pyridin-3-ylmethoxy)-naphthalene-2-carboxylic acid methyl ester in 4 ml 2,2,2-trifluoroethanol containing 5% of water was added 0.55 g sodium methoxide. The reaction was heated to 165° C. for 1 h using a microwave reactor. The reaction was then poured into ice-water, the pH was adjusted to 4 using 2 M hydrochloric acid and the precipitated product was collected by filtration and dried in vacuo yielding 0.22 g of 1-[6-(2,2,2-trifluoro-ethoxy)-pyridin-3-ylmethoxy]-naphthalene-2-carboxylic acid.
