methyl propiolate and of methyl 3-diethylaminoacrylate has yielded a novel series of 6-unsubstituted 3,4-dihydropyrimidin-2(1H)-ones. The successie oxidation of the pyrimidine ring, chlorination of the 2-oxo group, and substitution of the chlorine atom by an aromatic amine give previously unknown 2-(arylamino)pyrimidines. 2-Oxo- and 2-(arylamino)pyrimidine-5-carboxylic acids have been obtained.
