| titleOfInvention | Synthetic method of 1,2-dimethyl-1,4,5,6-tetrahydropyrimidine |
| abstract | According to the synthesis method of the 1,2-dimethyl-1,4,5,6-tetrahydropyrimidine, thioacetamide or hydrogen sulfide is added as a catalyst, so that the reaction time of N-methyl propane diamine and acetonitrile is greatly shortened, high yield is obtained in a short reaction time, and the reaction economy is greatly improved. |
