As a common heterocyclic compound, it belongs to benzoxazole compound, name is 5-Bromobenzo[d]oxazole, and cas is 132244-31-6, its synthesis route is as follows.,132244-31-6
10.0 grams (g) (50.5 millimoles, mmol) of 5-bromobenzo[d]oxazole, 15.4 g (60.6 mmol) of bis(pinacolato)diboron, 2.06 g (2.52 mmol) of PdCl2(dppf)¡¤CH2Cl2, and 14.9 g (152 mmol) of potassium acetate were dissolved in 168 milliliters (mL) of dimethylformamide (DMF), and stirred at a temperature of 100 C. for 20 hours. After the reaction was completed, the reaction product was cooled to room temperature and filtered through silica gel under reduced pressure, and a filtrate was concentrated under reduced pressure. The product obtained therefrom was separated by silica gel column chromatography. The product was recrystallized with dichloromethane (DCM)/n-hexane as an eluent to obtain 8.91 g (yield: 72%) of Intermediate (A). (0346) LC-Mass (calc: 245.12 g/mol, found: M+1=246 g/mol).
With the complex challenges of chemical substances, we look forward to future research findings about 132244-31-6,belong benzoxazole compound
