A series of new 6-unsubstituted 3,4-dihydropyrimidin-2(1H)-ones have been obtained from methyl propiolate, as well as from methyl 3-diethylaminoacrylate, using the Biginelli reaction. By subsequent oxidation of the pyrimidine reing, clorination of the 2-oxo group, and substitution of the chlorine atom by an aromatic amine they have been converted into heretofore unknown 2-(arylamino)pyrimidines. 2-Oxo- and 2-(arylamino)pyrimidine-5-carboxylic acids also were obtained.
