Product Description

Methyl 4-amino-2-methoxybenzoate has the cas number of 27492-84-8,The process is as following:Add 2 kg of p-aminosalicylic acid and 2.3 kg of ground potassium hydroxide to a four-necked flask. Add 6 liters of acetone solution and stir vigorously. The temperature was lowered to 25 ° C and 3 liters (31.68 mol) of dimethyl sulfate began to be added dropwise. After the addition was completed, the reaction was continued for 5.5 hours. After the reaction was completed, the solvent was removed by rotary evaporation and dissolved in 8 liters of water. The mixture was extracted three times with 25 liters of ethyl acetate and finally combined with ethyl acetate. The mixture was rotary evaporated to dry 2.18 kg of methyl 4-amino-2-methoxybenzoate cas 27492-84-8 . In the preparation process of amisulpride, some enterprises directly using 4-amino-2-methoxybenzoate as raw material and take amino protection with acetic anhydride, concentrated sulfuric acid sulfonated, phosphorus pentachloride, sodium sulfite reduction, B Alkylation, methyl ester hydrolysis, recrystallization to give the final product.
