Title: The Innovative Contributions of Hans-Reinhold Dieter
Introduction
Hans-Reinhold Dieter, an accomplished inventor based in Darmstadt, Germany, has made significant contributions to the field of pharmaceuticals. With a total of four patents to his name, Dieter has been at the forefront of developing innovative methods for synthesizing important chemical compounds that serve as precursors to active pharmaceutical ingredients.
Latest Patents
Dieter's latest innovations focus on the production of azaphenothiazines. His first notable patent describes a method for producing azophenothiazine derivatives featuring a range of substituents, including alkyl, alkoxy, halogen, hydrogen, carboxy, and carboxy alkyl groups. This process involves reacting a 2-chloropyridine with a 2-mercaptoaniline or a dimer of 2-(2-mercaptophenylamino)pyridine in an inert solvent, such as methylpyrolidone, with the presence of an oxidizing agent like performic acid.
His second notable patent outlines a method for creating 6-aza-benzo[b]-phenothiazine derivatives, where substituents can include hydrogen, lower alkyl, lower haloalkyl, carboxyl, or carboxy alkyl groups. This method consists of reacting 2-quinoiline derivatives with appropriate 2-mercaptoaniline derivatives or their dimers under oxidative or free radical conditions. The resulting 6-aza-benzo[b]-phenothiazine derivatives are recognized as valuable precursors for pharmaceutical substances such as pipacetate, isothioperdyl, and prothiperdyl.
