19932-85-5, 6-Bromobenzo[d]oxazol-2(3H)-one is a benzoxazole compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
General procedure: General Procedure III: Synthesis of compounds of Formula II (Scheme 2b) VI, e.g. bromo-substituted 3H-l,3-benzoxazol-2-one, (1 eq.) was suspended in a 1:1 toluene/EtOH mixture (10 mL per mmol VI). The boronic acid VII (1.5 eq.) was added followed by aq. Na2C03 (2 M, 0.55 mL per mmol VI, 1.1 eq.). The resulting suspension was degassed under nitrogen for 10 min, followed by addition of tetrakis(triphenylphosphine) palladium(O) (0.1 eq.) and heating under microwave irradiation at 100 C for 30 min. The reaction mixture was diluted with EtOAc (40 mL per mmol VI), and water (40 mL per mmol VI) was added. The two phases were separated and the aqueous layer was extracted with EtOAc (2 chi 40 mL per mmol VI). The combined organic phases were dried over Na2S04, evaporated on celite, and the compound was purified by column chromatography using the Teledyne ISCO apparatus (cyclohexane:EtOAc).
19932-85-5, 19932-85-5 6-Bromobenzo[d]oxazol-2(3H)-one 29859, abenzoxazole compound, is more and more widely used in various fields.
