The present invention relates to a novel polymorph of isobutyric acid 2-((R)-3-diisopropylamino-1-phenylpropyl)-4-(hydroxymethyl) phenyl ester hydrochloride represented by the following structural formula-1a and process for its preparation.
摘要:
The invention concerns a process for the preparation of 2-(3-N,N- diisopropylamino-l-phenylpropyl)-4-hydroxymethyl-phenol and its derivatives, particularly the corresponding (R) 4-trityloxymethyl derivative, useful as intermediate form in the synthesis of Fesoterodine and its salts, in particular for the preparation of Fesoterodine fumarate salt.
摘要:
The compounds of Formula I are prodrugs of CETP inhibitors having a central oxazolidinone ring. The compounds cyclize by the elimination of HX to form an oxazolidinone ring after administration to a patient.
摘要:
Es werden die Verbindungen 1-Phenyl-2-aminomethylnapthalin-Derivate der allgemeinen Formel (1) beschrieben sowie Verfahren zu ihrer Herstellung. 1-Phenyl-2-aminomethylnapthaline haben in Zellkulturmodellen Antitumor-Eigenschaften. Weiterhin stellen diese Substanzen Inhibitoren für neurodegenerative Erkrankungen dar und zeigen eine ausgeprägte antiprotozoische Aktivität.
摘要:
The invention relates to highly pure, crystalline, stable compounds of 3,3-diphenylpropylamine derivatives, in the form of their salts, a method for their production and highly pure, stable, intermediate products. The method is particularly characterized by regio- and chemo-selectivity and high yields and provides salts of phenolic monoesters of 3,3-diphenylpropylamines, which are particularly suitable for application in technical pharmaceutic formulations. Preferred compounds are R -(+)-2-(3-diisopropylamino-1-phenylpropyl)-4-hydroxymethylphenyl isobutyrate hydrogenfumarate and R -(+)-2-(3-diisopropylamino-1-phenylpropyl)-4-hydroxymethylphenyl isobutyrate hydrochloride hydrate. The method further provides essential, stable, crystalline intermediate products for the production of the above salts. A preferred intermediate product is R -(-)-3-(3-diisopropylaminophenylpropyl)-4-hydroxybenzoic acid methyl ester.
摘要:
Para-substitued benzyl amines of general formula (I) in which W is a carbonyl group or a single bond, R1 is a lower alkyl group, R2 is an alkyl radical with 5 to 20 carbon atoms which may be branched and contain 1 to 3 double bonds, in addition a saturated cycle of 3 to 7 carbon atoms may be integrated into the chain or included as substituents, and may be substitued by one or more aromatic rings and contain a sulphur or oxygen atom, X is a group of the general formula: OR?3 or NR4R5¿ in which R3 stands for a lower alkyl, lower alkyl carbonyl, lower alkoxycarbonyl, mono lower alkyl aminocarbonyl, di lower alkyl aminocarbonyl group or a hydrogen atom, R4 is a lower alkyl group or a hydrogen atom and R5 is a hydrogen atom, a lower alkyl, lower alkyl carbonyl, lower alkoxy carbonyl, aminocarbonyl, mono lower alkyl aminocarbonyl or di lower alkyl aminocarbonyl group, Y is a hydrogen atom or a methyl group, and addition salts with physiologically acceptable acids and medicaments containing them.
