Adding a certain compound to certain chemical reactions, such as: 6326-79-0, name is 6-Bromoisatin, belongs to indolines-derivatives compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 6326-79-0, Computed Properties of C8H4BrNO2
A mixture of 6-bromoisatin (226 mg, 1 mmol), malonic acid, (114 mg, 1.1 mmols) and sodium acetate (103 mg, 1.25 mmols) and acetic acid (2.5 ml) the was stirred under a nitrogen atmosphere for 5 h. Additional sodium acetate (100 mg) was added and the resultant mixture was heated overnight. The reaction mixture was cooled to room temperature, excess acetic acid was removed under reduced pressure and the resultant pinkish brown solid was washed with copious amounts of water and dried under vacuum to obtain the desired product (234 mg, 88%). ‘H NMR (300 MHZ, DMSO-d6): 6. 88 (s, 1H), 7.44 (d, 1H), 7.58 (s, 1H), 8.18 (d, 1H), 12.11 (br s, 1H), INLZ 268
