2-METHOXY-4-AMINO-5-ETHYLSULFAMOYL BENZOIC ACID - Reference Information

LogP	0.46
Introduction	amilic acid is also called amisopride acid, amilic acid, an intermediate of amisulpride, an intermediate of amsulpiride. Amisulpride, a new non-classical antipsychotic drug with significant advantages against negative symptoms, can be produced by using amitric acid, it is used to treat acute or chronic schizophrenia characterized by positive symptoms (e. G., delirium hallucination Cognitive Disorder) and/or negative symptoms (e. G., slow-reacting apathy and social withdrawal).
Application	synthesis of impurity H: add 25.9g(0.10mol) of amitric acid to ML of acetone, cool to 0 ℃, control temperature 0 ℃ slowly drop 13.1g(0.13mol) triethylamine, control temperature 0 ℃ slowly drop add 14.1g(0.13mol) ethyl chloroformate, 18.4g(0.13mol) of n-ethyl-2-methylaminomethylpyrrolidine was slowly added dropwise under the control of temperature of 0 ℃, the temperature was raised to 28 ℃ for 16 hours, and of drinking water was added, adjust the pH to 20% with 10.0 sodium hydroxide solution, cool down to 0 ℃, maintain crystallization for 12 hours, filter, filter cake drying to obtain impurity H 26.8g, yield 70%.
