Latest Patents
Dembkowski's most recent patents encompass advanced methods for synthesizing complex bisphosphonic acid compounds. His first notable invention involves a process for the preparation of [1-hydroxy-2-(1-imidazol-1-yl)-ethylidene]bisphosphonic acid. This method includes the reaction of an aqueous solution of 1H-imidazole-1-acetic acid hydrochloride with phosphorus trichloride. Following the removal of excess phosphorus trichloride, water is added, and hydrolysis of the reaction products occurs. To isolate the product, the post-reaction mixture is filtered, and an anti-solvent is added to crystallize the [1-hydroxy-2-(1-imidazol-1-yl)-ethylidene]bisphosphonic acid monohydrate.
The second patent details a process for the preparation of [1-hydroxy-2-(3-pyridinyl)ethylidene]bisphosphonic acid and its hemipentahydrate monosodium salt. This invention outlines several steps beginning with the reaction of an aqueous solution of 3-pyridyl acetic acid hydrochloride with phosphorus trichloride, subsequent hydrolysis, and the isolation of the crystalline product. The process concludes with the drying of the obtained hemipentahydrate monosodium salt of [1-hydroxy-2-(3-pyridinyl)ethylidene]bisphosphonic acid.
