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
[0156j Triethylamine (0.72 g, 1.0 mL, 7.1 mmol) was added to a stirring a mixture of 6- bromo-2benzoxazilinone (0.89 g, 4.2 mmol) and trityichioride (1.21 g, 4.4 mmol) in CH2C12 (10 mL) for a period of 10 mm. The reaction was monitored by TLC (silica gel) and concentrated after 1 h. The concentrate was diluted with water and sonicated to form a heterogeneous solution. The resulting off-white solid was suction filtered and dried to provide 1 -trityl-6-bromo-2- benzoxazilinone (2.0 g). LCMS: rt 9.45 mm (A), purity 96 %, MS (mle) 456 (MHj.
19932-85-5, As the paragraph descriping shows that 19932-85-5 is playing an increasingly important role.
