-
Paragraph 0018; 0022, (2016/10/27)
The invention discloses a synthetic method of 4-amino-5-chloro-2-methoxyl benzoic acid, wherein the synthetic method includes the steps of dimethyl sulphate methylation, N-chloro-succinimide chlorination, alkaline hydrolysis de-esterification and hydrochloric acid acidification to prepare an intermediate product, wherein aminosalicylic acid, which is low in cost and easy to obtain, is employed as a raw material. The synthetic method is reasonable and simple in process route design, is mild in reaction conditions, is easy to industrially operate, is low in costs of raw material and devices, is high in yield and product quality, and is effectively reduced in production cost.

Irritable bowel syndrome is the most common functional gastrointestinal disorder characterized by chronic abdominal pain or discomfort in association with a change in bowel habit. 5-HT receptor modulators have been developed as IBS therapeutic agents and proved to be effective in the treatment of the disease. In this letter, 12 berberine derivatives were designed and synthesized as 5-HT receptor modulators. Preliminary biological tests suggested that the new compounds exhibited promising activity for IBS therapy.

, p. 381 - 394 (2007/10/02)
N-(8-Isopropyl-nortropan-3-α-yl)-2-methoxy-4-amino-5-chlorobenzamide has been synthesized and its crystal and molecular structures determined by X-ray diffraction, IR, 1H-NMR and 13C-NMR methods.The pyrrolidine and piperidine rings adopt a flattened N-8 envelope and distorted chair conformation puckered at N-8 and flattened at C-3 respectively, with the N-isopropyl substituent and the amido group in axial position with respect to the piperidine ring.A great predominance in solution of the conformer observed in the solid state is proposed.

, (2008/06/13)
The invention relates to aromatic amides N-substituted by heterocyclic groups. More particularly, the invention relates to substituted benzoic acid amides of 1-arylalkylamino or aminoalkyl-N-heterocyclic rings and to pharmaceutical compositions thereof, which have the ability to antagonize the effects of dopamine or dopaminergic agents of endogenous or exogenous origin and which may be used for the treatment of nausea and vomiting resulting from gastrointestinal disorders, congestive heart failure, post operative conditions, etc., other gastrointestinal disorders such as dyspepsia, flatulence, bile regurgitations, hiatus hernia, peptic ulcer, reflux aerophagitis, gastritis, duodenitis, and cholethiasis, and a variety of conditions affecting the central nervous system such as acute and chronic psychoses, maniacal psychosis, schizophrenias, serious disturbances of behavior and non-melancholic depressive state and migraine.
