The invention discloses a synthesis method of 1,2-dimethyl-1,4,5,6-tetrahydropyrimidine. A novel route is chosen, reactions are efficiently and quickly carried out under the assistance of microwaves,and the product yield is high. The synthesis method has the advantages of simple reaction route, easy operation, short reaction time, and high yield.

N,N′-Dimethyl cyclic ketene N,N′-acetals react with two or three equivalents of isocyanates to generate tetrasubstituted push-pull alkene derivatives in one-pot sequential reactions. X-ray crystallography showed significant elongations and out of plane distorsions of the polarized carbon-carbon double bonds.
