Latest Patents

Mettler's latest patents include a process for the production of 4-Amino-2-chloro-5-cyano-6-(methylthio)primidine. This compound is produced from dicyanoketene dimethyl thioacetal and cyanamide through a condensation reaction in the presence of a base, followed by cyclization with hydrochloric acid. The dicyanoketenedimeth thioacetal is synthesized by reacting malononitrile with carbon disulfide and a base, followed by methylation with dimethyl sulfate. This reaction sequence yields the pyrimidine derivative in good yield and is practically free of by-products. Another significant patent is for the production of 1-(aminomethyl)cyclohexane acetic acid, a pharmaceutical agent used as an anticonvulsant. This process involves decarbalkoxylation of a (1-cyanocyclohexyl)malonic acid dialkyl ester to obtain the corresponding (1-cyanocyclohexyl)acetic acid alkyl ester, which is then transesterified with benzyl alcohol and hydrogenated to form the final product.
