0001-3 A solution of bromine (0.99 mL) in acetic acid (2.5 mL) was added dropwise to a mixture of 2-chloro-1,5-naphthyridine (2.88 g) and sodium acetate (2.89 g) in acetic acid (15 mL) at 85 C., and acetic acid (2 mL) was added thereto, followed by stirring at 85 C. for 3 hours. The reaction mixture was cooled to room temperature, and added dropwise to a 6 mol/L sodium hydroxide aqueous solution (60 mL) under ice-cooling. The solid matter was collected by filtration, suspended in methanol (5 mL), and subjected to an ultrasonic treatment. The solid matter was collected by filtration, and washed with methanol (3 mL). The obtained solid was suspended in a 75 v/v % methanol aqueous solution (8 mL), the resultant product was subjected to an ultrasonic treatment, and the solid matter was collected by filtration, thereby obtaining 7-bromo-2-chloro-1,5-naphthyridine (3.33 g) as a pale yellow solid. MS m/z (M+H): 243.
7689-62-5 2-Chloro-1,5-naphthyridine 15153031, anaphthyridine compound, is more and more widely used in various.
