Title: The Innovative Contributions of Gary Ryan
Introduction
Gary Ryan, an accomplished inventor based in Visp, Switzerland, has made significant strides in the field of chemical processing and synthesis. With three notable patents to his name, Ryan showcases his expertise in developing unique processes that enhance the production of valuable chemical compounds.
Latest Patents
Ryan's most recent patent focuses on a specialized process for the production of 4-Amino-2-chloro-5-cyano-6-(methylthio)primidine. This innovative method involves synthesizing the compound from dicyanoketene dimethyl thioacetal and cyanamide through a condensation reaction in the presence of a base, followed by cyclization with hydrochloric acid. The dicyanoketene dimethyl thioacetal is generated from malononitrile, carbon disulfide, and a base, with subsequent methylation using dimethyl sulfate. This reaction sequence yields the pyrimidine derivative with a high yield and minimal by-products.
Another of Ryan's important patents details a method for producing 1-(N-methanesulfonyl-N-methylaminosulfonyl)-3-(2-pyrimidyl) urea derivatives (MMSPH). In this innovative process, methanesulfonylmethylamine (MMSA) is first transformed using chlorosulfonylisocyanate (CSI) to form a 1-methanesulfonyl-1-methyl-3-(N-methanesulfonyl-N-methylaminosulfonyl) urea derivative (MMMSH). This intermediate is then reacted with a 2-aminopyridine to achieve the final product.
