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.
Method N B-9 Ex. 3 To a stirred solution of Intermediate B-9 (400 mg, 0.937 mmol) and 3-bromo-8-chloro-l,7- naphthyridine (252 mg, 1.03 mmol) in THF (10 mL) was added LHMDS (1 M in THF, 3.28 mL, 3.28 mmol) at RT. The mixture was stirred at 45 C overnight, quenched with NH CI (sat.) and extracted with DCM. The combined organic extracts were dried over Na2S04 and concentrated. The residue was treated with 5 mL of DCM and 0.5 mL of TFA and stirred at 25 C for 2 h. The mixture was neutralized with NaHC03 and extracted with DCM. The organic layer was washed with brine, dried over Na2S04 and concentrated. The residue was purified by silica column chromatography (PE: EtOAc = 1 : 1) to afford example 3. MS for example 3: m/e = 533 and 535 (M+l).
1260670-05-0, As the rapid development of chemical substances, we look forward to future research findings about 1260670-05-0
