标题:Method for obtaining a pharmaceutically active compound (Irbesartan) and its synthesis intermediate

摘要:It is provided a method for obtaining Irbesartan polymorph A, with few synthesis steps, by coupling the intermediate of formula (II) with the compound of formula (III), neutralising one of its alkaline salts in an aqueous medium and recrystallising the crude product obtained. The utilisation of said method obviates protection and deprotection of the tetrazole ring and is therefore of considerable interest for obtaining Irbesartan on a large industrial scale. The invention also refers to the synthesis intermediate of formula (II).

标题 :Synthesis and methods of use of purine analogues and derivatives
发明人：FICK DAVID B; FOREMAN MARK M; GLASKY ALVIN J
摘要:A purine derivative or analogue comprises a 9-atom bicyclic moiety, moiety A, linked through a linker L to a moiety B, where B is a carboxylic acid, a carboxylic acid ester, or a moiety of the structure N(Y 1 )—D, where Y 1 can be one of a variety of substituents, including hydrogen or alkyl, and D is a moiety that enhances the pharmacological effects, promotes absorption or blood-brain barrier penetration of the derivative or analogue. The moiety A has a six-membered ring fused to a five-membered ring. The moiety A can have one, two, or three nitrogen atoms in the five membered ring and has two nitrogen atoms in the six-membered ring. The moiety A can be a purine moiety. The moiety B can be one of a variety of moieties, including moieties having nootropic activity or other biological or physiological activity.
