Synthesis of 1‐alkyl‐5‐phenyl‐4(1H)pyrimidinones

Abstract
1‐Alkyl‐5‐phenyl‐4(1H)pyrimidinones are readily synthesized by condensing β‐(dimethylamino)‐N‐[(dimethylamino)methylene] atropamides with methyl or ethyl amine. The latter compounds are prepared from phenylacetamides and dimethylformamide dimethyl acetal.
