To a solution of 8-chloro-1,7-naphthyridin-3-ol (618 mg, 3.42 mmol) in DMF (11 ml) were added bromobutyne (882 mg, 6.67 mmol), cesium carbonate (3233 mg, 9.92 mmol). The reaction mixture was heated at 50° C. for 0.5 h. It was quenched with water, and light brown precipitate was formed. It was then collected by Buchner funnel to yield 3-(but-2-yn-1-yloxy)-8-chloro-1,7-naphthyridine (550 mg, 74% yield) as light brown solid. MS m/z: 233.1 [M+H].
