| titleOfInvention | Method for producing aminoimidazole derivative |
| abstract | Provided is a production method capable of obtaining an aminoimidazole derivative in high yield from diaminomaleonitrile as a starting material. A process of obtaining an alkyl N- (2-amino-1,2-dicyanovinyl) formimidate derivative by reacting diaminomaleonitrile with an orthocarboxylic acid triester in the presence of a strong acid, the formimidate derivative A step of reacting ammonia water, an aqueous amine solution or the like to obtain an N- (2-amino-1,2-dicyanovinyl) formamidine derivative, and a step of cyclizing the formamidine derivative in the presence of a basic aqueous solution Are carried out in the presence of an aprotic organic solvent to obtain an aminoimidazole derivative represented by the following formula. In the formula, R 1 and R 3 are each independently a hydrogen atom, an alkyl group which may have a substituent, or an aryl group which may have a substituent. R 4 is -CN or -CONH 2. [Selection figure] None |
