Reference of 1647-23-0, These common heterocyclic compound, 1647-23-0, name is 1-Bromo-3,3-dimethylbutane, 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.
4-Bromo-2-hydroxy pyridine (600mg, 3.4mmol)taken up in dry DMF under nitrogen. Sodium hydride 60% in oil (165mg, 4.lmmol) added and stirred 30 minutes. Lithiumbromide (598mg, 6.8mmol) added and stirred 1 hour. 1-Bromo-3,3-dimethyl butane (870uL, 6.8mmol) added and stirred 3 days. Reaction was reduced in vacuo and taken up in DCM. This was washed with water, iN NaOH then dried over magnesium sulfate filtered and reduced in vacuo to obtain 860 mg crude product to be used as is in next step. LRMS (ESI) m/z 258/260 [(M+H)], calc?d for C11H16BrNO: 258.16.
Statistics shows that 1-Bromo-3,3-dimethylbutane is playing an increasingly important role. we look forward to future research findings about 1647-23-0.
