Synthesis of A Pyrimidine Pharmaceutical Intermediates
Abstract: Pyrimidine compounds are a class of hetero-cyclic compounds containing nitrogen, because it shows good biological activity in bio-pharmaceuticals have a wide range of applications. Pyrimidine compounds are widely used in the medical field, currently these compounds as intermediates in the synthesis of a wide variety of drugs. Some medicines wide application, fast efficacy and toxicity, it has an irreplaceable role of other drugs and has been widely used in clinical treatment. This paper describes the status and application of pyrimidines and several different methods of synthesis of pyrimidinone. Now after the adoption of the summary of the multi-party literature to determine the final synthetic route. Experiments using ethyl 4-chloroacetoacetate and 1-phenyl-5-mercapto-tetrazole as a starting material, we get the first intermediate product FETCL-6609. Then we use the FETCL-6609 and guanidine hydrochloride to get the second intermediate product FETCL-6610. At last we use 4-(chloromethyl)benzoyl chloride and FETCL-6610 to get the ultimate goal of product FETCL-6620. The experimental synthetic route have advantages of it has a high yield and convenient for subsequent processing.
