Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 59557-91-4, name is 4-Bromo-2-methoxyaniline, This compound has unique chemical properties. The synthetic route is as follows., Product Details of 59557-91-4
Intermediate 10 4-Bromo-2-methoxy-N /V-dimethylaniline [00406] Formaldehyde (3.7 mL, 49 mmol, 37% aqueous) and acetic acid (57 uL, 1 mmol) were added to a solution of 4-bromo-2-methoxyaniline (2.0 g, 9.9 mmol) in methanol (10 mL) at 25 C. The mixture was stirred for 2 h, and then sodium cyanoborohydride (3.11 g, 49.5 mmol) was added in portions. The resulting mixture was stirred for 12 h, poured into a saturated NaHC03 solution (40 mL), and then extracted with ethyl acetate (3 x20 mL). The combined organic phases were washed with brine (2×20 mL), dried over anhydrous Na2S04, filtered and concentrated. The residue was purified by column chromatography (Si02, petroleum ether/ethyl acetate; 15/1) to give 4-bromo-2-methoxy-N,N-dimethylaniline (2.0 g, 80%) as a brown oil. 1H MR (CDC13): delta 7.02 (dd, 1H), 6.95 (d, 1H), 6.78 (d, 1H), 3.87 (s, 3H), 2.76 (s, 6H); MS: 230.0 [M+H]+.
Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 59557-91-4.
