3-Bromo-8-chloro-1,7-naphthyridine, cas is 1260670-05-0, it is a common heterocyclic compound, the naphthyridine compound, its synthesis route is as follows.
To a solution of 3-bromo-8-chloro-1, 7-naphthyridine (2.43g) in toluene (30mL) , EtOH (10mL) , and 10%Na2CO3aq. (10mL) Pd (dppf) Cl2.DCM (420mg) was added. 4, 4, 5, 5-tetramethyl-2-vinyl-1, 3, 2-dioxaborolane (3.1g) was added dropwise under N2protection. The mixture was allowed to stir at 100 for 16 h. The reaction was quenched by H2O (50mL) and extracted by EtOAc for 3 times. Organic layer was combined and washed with brine. The resulting solution was concentrated and purified by silicagel (eluting with hexane-EtOAc using a gradient from 8: 1 to 5: 1) to afford 8-chloro-3-vinyl-1, 7-naphthyridine (1.1g) as a brown solid., 1260670-05-0
1260670-05-0 is used more and more widely, we look forward to future research findings about 3-Bromo-8-chloro-1,7-naphthyridine
