실험 절차

A solution of 4-(2-benzyloxyethyl)-6-fluoro-1-(3,4,5-tribromobenzyl)-1,2-dihydro-2-oxoquinoline (6.0 g.) in a mixture of dioxan (50 ml.), ethanol (50 ml.), and concentrated hydrochloric acid (2 ml.) was hydrogenated at atmospheric pressure over 5% palladium on carbon (1 g.). The theoretical quantity of hydrogen (390 ml. at N.T.P.) was absorbed in four minutes. The hydrogenation was stopped and the mixture filtered. Evaporation of the filtrate gave the crude product which was recrystallised twice from methanol to give 4-(2-hydroxyethyl)-6-fluoro-1-(3,4,5-tribromobenzyl)-1,2-dihydro-2-oxoquinoline, m.p. 199°-201° C., in 71% yield.
