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.
To a 100 mL round bottom was added 5-bromobenzoxazole (1.06 g, 5.35 mmol), 4-formylphenyl boronic acid (883 mg, 5.89 mmol), bistriphenylphosphine palladium chloride (350 mg, 0.5 mmol), potassium phosphate (3.4 g, 6.05 mmol) and DME/H2O (3/1, 20 mL). The reaction mixture was stirred at 80 degrees C. overnight, filtered through celite and diluted with ethyl acetate. The organic layer was washed with saturated bicarbonate solution and then brine and was dried with MgSO4. The mixture was concentrated and purified on silica gel column (40 g) using a gradient of hexanes and 40% ethyl acetate/hexanes to afford 4-(1,3-benzoxazol-5-yl)benzaldehyde.LC/MS: (M+1) 224.03, 2.20 min (LC/MS Method A).
132244-31-6, In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles.,132244-31-6 ,5-Bromobenzo[d]oxazole, other downstream synthetic routes, hurry up and to see
