132244-31-6, 5-Bromobenzo[d]oxazole is a benzoxazole compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
To a solution of 5-bromobenzo[d]oxazole (1.2 g, 6.06 mmol, 1 eq.) in DMF (10 mL) was added 5-(4,4,5,5-Bis(pinacolato)diboron (1.68 g, 1.66 mmol, 1.1 eq.), KOAc (1.7 g, 18.09 mmol, 3 eq.), and PdCl2(dppf)?DCM complex (247 mg, 0.23 mmol, 0.05 eq.). The reaction mixture was deoxygenated with N2 and the reaction mixture was stirred at 80 C. for 18 h. The progress of the reaction was monitored by LCMS The reaction mixture was cooled to RT, diluted with water (50 mL) and extracted with ethyl acetate (2*50 mL). Combined organic layer was washed with brine (20 mL) and dried over sodium sulfate. Removal of solvent under reduced pressure gave crude which was purified by flash chromatography(0-100% Hexane-EtOAc) to afford 5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzo[d]oxazole (0.900 g, 60%) as off white solid. LCMS: 245, 247 [M+1]+
132244-31-6, 132244-31-6 5-Bromobenzo[d]oxazole 21749504, abenzoxazole compound, is more and more widely used in various fields.
