REACTIONS OF ARYLPROPIOLAMIDES WITH ARYLACETAMIDES
Al-Arab, Mohammad M.
, p. 2910 - 2913 (2007/10/02)
The reaction of 3-phenylpropiolamide with phenylacetamide yielded 2-benzyl-4-phenyl-6-pyrimidone, whilst that of o-chlorophenylpropiolamide with phenylacetamide or p-chlorophenylacetamide yielded the 4-(o-chlorophenyl)pyrimidine-2,6-dione.The reaction products were identified from their spectral analysis.
