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
Step 2: Bromide 1 (12.8 g, 59.6 mmol) was dissolved in anhydrous THF (220 mL), and the solution was cooled to ?78 C. Solutions of MeMgBr (21.9 mL of a 3.0 M solution in Et2O, 65.6 mmol), sec-BuLi (50.4 mL of a 1.3 M solution in cyclohexane, 65.6 mmol), and 1,4-Cyclohexanedione mono-ethylene ketal (11.2 g, 71.5 mmol) in anhydrous THF (10 mL) were added sequentially at 30-minute intervals. After the final addition, the reaction mixture was allowed to warm to room temperature. The reaction was quenched by the addition of 1N HCl (25 mL). The reaction mixture was diluted with EtOAc (500 mL), washed with saturated NaCl (250 mL), dried (Na2SO4), filtered, and concentrated under reduced pressure to provide a mixture of 2 and 3, as a brown oil.
19932-85-5, As the paragraph descriping shows that 19932-85-5 is playing an increasingly important role.
