実験手順

A solution of 6-benzyloxy -naphthalene-2-carboxylic acid benzyl ester (52) (1 equi.) and potassium hydroxide (3.5 equi.) in water-ethanol (1:1) (25 mL/mmole) was stirred at 80 C temperature for 2 h., cooled to room temperature and quenched with hydrochloric acid (5%), filtered resulted white solid, washed with water, and dried under vacuum to 6-benzyloxy-naphthalene-2-carboxylic acid (53) as a white solid (81%).
