Synthetic Route of 6358-77-6, A common heterocyclic compound, 6358-77-6, name is 5-Bromo-2-methoxyaniline, molecular formula is C7H8BrNO, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
Intermediate 14: step a 4-Bromo-2-isothiocyanato-1-methoxy-benzene A solution of sodium bicarbonate (3.74 g, 44.5 mmol) in water (75 mL) was added to commercially available 5-bromo-2-methoxy-phenylamine (3 g, 14.8 mmol) in chloroform (75 mL). Thiophosgene (1.42 mL, 18.6 mmol) was then added. The biphasic solution was stirred at room temperature for 1 h. The phases were separated and the aqueous phase was extracted with CH2Cl2. The organic phase was dried (Na2SO4), filtered, and concentrated, yielding the crude title compound as an off-white solid.
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
