Micro reaction system and method for preparing 2-methyl-4-amino-5-cyanopyrimidine using same |
| abstract |
Disclosed herein relates to pharmaceutical engineering, and more particularly to a micro reaction system and a method for preparing 2-methyl-4-amino-5-cyanopyrimidine using the same. An acetamidine hydrochloride solution and an (dimethylaminomethylene)malononitrile solution are separately pumped into the micro reaction system including a micromixer and an agitating microchannel reactor in communication at the same time for a continuous condensation-cyclization reaction to obtain 2-methyl-4-amino-5-cyanopyrimidine. |
