실험 절차
Ethyl 4-hydroxy-3,4-dihydro-1,5-naphthyridine-3-carboxylate (1.8 g, 8.2 mmol) was dissolved in 4% aqueous sodium hydroxide (80 ml). The reaction mixture was heated to reflux for 4 hours, cooled to room temperature, and then adjusted to pH=4 with 2N hydrochloric acid. The reaction mixture was filtered to give 4-hydroxy-3,4-dihydro-1,5-naphthyridine-3-carboxylic acid.
