Adding a certain compound to certain chemical reactions, such as: 56741-34-5, name is Methyl 5-amino-2-fluorobenzoate, belongs to esters-buliding-blocks 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 56741-34-5, Recommanded Product: Methyl 5-amino-2-fluorobenzoate
General procedure: To a solution of 11a (500 mg, 1.85 mmol) in acetone (10 mL) was added 12 (380 mg, 1.85 mmol) and pyridine (0.45 mL, 5.54 mmol).The mixture was stirred at 55 C for 1 h. The mixture was concentrated,diluted with ethyl acetate and washed with 1M HCl and brine twice.Then, the ethyl acetate layer was dried over anhydrous sodium sulfate andconcentrated to give the crude product. The crude product was purified bysilica column eluting with petroleum ether/ethyl acetate (5/1-2/1) to givethe desired product (0.33 g, yield 44.3%) as grey solid
