실험 절차

A mixture of ethyl 6-bromo-4-hydroxy-7-methyl-1,8-naphthyridine-3-carboxylate (6.7 g), sodium hydroxide pellets (1.7 g) and water (50 ml) was heated at 180° C. in a pressure vessel for 18 hours. The mixture was cooled and filtered to give 6-bromo-7-methyl-1,8-naphthyridin-4-ol, m.p. >250° C.
