The important role of 3-Bromo-8-chloro-1,7-naphthyridine

1260670-05-0 is used more and more widely, we look forward to future research findings about 3-Bromo-8-chloro-1,7-naphthyridine

As a common heterocyclic compound, it belongs to naphthyridine compound, name is 3-Bromo-8-chloro-1,7-naphthyridine, and cas is 1260670-05-0, its synthesis route is as follows.,1260670-05-0

Step 1 To a mixture of 3-bromo-8-chloro-l ,7-naphthyridine J-1 (4.00 g, 16.4 mmol), but-2-yn-l-ol (1.78 g, 24.6 mmol), Cs2C03 (8.03 g, 24.6 mmol), and 5-(di-ieri-butylphosphino)-l’,3′,5′- triphenyl-rH-l ,4′-bipyrazole (1.67 g, 3.29 mmol) in THF (40 mL) was added diacetoxypalladium (0.574 g, 1.64 mmol) under N2. The mixture was stirred at 70 C for 4 h and concentrated; the residue was purified directly by silica column chromatography (PE: EtOAc = 3: 1) to afford compound J-2. MS for J-2: m/e = 233 (M+l).

1260670-05-0 is used more and more widely, we look forward to future research findings about 3-Bromo-8-chloro-1,7-naphthyridine
