Adding some certain compound to certain chemical reactions, such as: 4093-29-2, name is Methyl 4-acetamido-2-methoxybenzoate, 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 4093-29-2. 4093-29-2
[0543] To a solution of 269-3 (4.46 g, 20 mmol), PdOAc (0.45 g, 2 mmol) and Cu(OAe)2 (7.26 g, 40 mmol) in 1.2-dichloroethane ( 150 mL) was added anhydrous CuBr2 (8.93 g. 40 mmol) under N2 atmosphere. The mixture was stirred at 90 C for 72 h. After cooling to r.t., the reaction was quenched by water, and filtered through a celite pad. The solution was washed with brine, dried by anhydrous Na2S04 and concentrated at low pressure. The residue was purified by flash column chromatography on silica gel (PE:EA 1 : 1 ) to give 269-4 (6.04 g, 51 .3%). +ESI-MS:m/z 303.7 [M+I I]
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 Methyl 4-acetamido-2-methoxybenzoate.
