Synthetic Route of 933190-51-3, These common heterocyclic compound, 933190-51-3, name is 8-Bromo-6-chloroimidazo[1,2-b]pyridazine, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
General procedure: To a solution of 6a-6c (1 mmol) in THF (5 mL) was addedmorpholine (or (S)-3-methylmorpholine, or 8-oxa-3-azabicyclo[3.2.1]octane) (1.2 mmol) and Et3N (2.2 mmol). The mixture washeated under reflux for 12 h. The crude product was extracted with CH2Cl2, dried over Na2SO4, purified over silica gel chromatographyeluting with PE and EtOAc to give 7a-7g [43].
Statistics shows that 8-Bromo-6-chloroimidazo[1,2-b]pyridazine is playing an increasingly important role. we look forward to future research findings about 933190-51-3.
