Novel and Efficient Synthesis of Pyrimidine Derivatives
摘要:
A new series of 1-alkyl-2-oxo-1,2-dihydro-pyrimidine-5-carboxalic acid amides is described. The reaction of N-((E)-3-(dimethylamino)-2-formylacryloyl) formamidine, an intermediate obtained by Vilsmeier-Haack formylation of acetonitrile with various mono-substituted ureas, provides such compounds in good yields.
