Hydrochloric Acid → 2-Ethyl-[1,6]naphthyridin-3-ol

Participants

Reaction Steps

4-Amino-pyridine-3-carbaldehyde (100 mg) and 1-bromo-butan-2-one (124 mg) were suspended in a 5 N aqueous sodium hydroxide solution (0.6 ml), and the suspension was hermetically sealed and, in this state, was allowed to stand for 3 days. The reaction solution was neutralized with 10% hydrochloric acid, the precipitate was then filtered, and the residue was washed with water and chloroform. The powder as the residue was dried under the reduced pressure to give 2-ethyl-[1,6]naphthyridin-3-ol (69 mg, yield 48%).
