실험 절차

A solution of 6-hydroxy-2-naphthoic acid (1.04 g) in a mixture of 10% sodium hydroxide aqueous solution (4.44 ml) and dimethyl sulfoxide (18 ml) was stirred for half an hour at 80° C. Then heptyl bromide (0.872 ml) was added thereto and stirred for 5 hours at 60° C. The reaction mixture was added to water (50 ml) and the mixture was adjusted to pH 3 with conc. hydrochloric acid. The resultant precipitate was collected by filtration and dried to give 6-heptyloxy-2-naphthoic acid (1.39 g).
