Action of Acetoacetic Ester on Amidins. Part III. — Pyrimidins. 



With the exception of formamidin all the amidins experimented with 

 form pyrimidins ; formamidin yields cyanacetoacetic ester. Aceta- 

 midin yields di-methyl-hydroxy-pyrimidin, propionamidin yields ethyl- 

 methyl-hydroxy-pyrimidin,
