  On reaction of phenylmagnesium bromide with ethyl ester of 5-chloro-2-methyl-, 5-chloro-2-methylthio-, 5-bromo-2-methylthio-4-pyrimidinecarboxylic acid and 2,4-dimethyl-5-pyrimidinecarboxylic acid (IIa, IIb, IIc, V) corresponding 4-pyrimidinyl- or 5-pyrimidinyl-diphenylmethanols (IIIa, IIIb, IIIc, VI) were obtained. On reaction of thionyl-bis-imidazole with these methanols (4- or 5-pyrimidinyl)-diphenyl-(1-imidazolyl)-methanes IVa, IVb, IVc and VII were prepared. Phenylmagnesium bromide reacted with ethyl 4-methyl-2-methylthio-5-pyrimidinecarboxylate (VIII) under formation of dihydro derivative IX. We were unable to prepare Grignard's reagent from 5-bromo-2-methylthiopyrimidine and magnesium; it reacted with ethylmagnesium bromide under formation of dihydro derivative I. 5-Chloro-2-methylthio-4-pyrimidinecarboxylic acid when heated with NaOH in dimethyl sulfoxide gave 5-hydroxy-2-methylsulfinyl-4-pyrimidinecarboxylic acid. Compounds IVb and IVc prevented the growth of Candida albicans in vitro at almost the same concentrations as clotrimazole.

  The reaction of open-chain and cyclohexane sym-2-dimethylaminomethylene-1,3-diones with amidines and guanidine in refluxing ethanol gave, generally in good yields, a series of 5-acylpyrimidines and 7,8-dihydroquinazolin-5(6H)-ones, respectively. With formamidine (and in part acetamidine), 2-formylimino-1,3-diones were formed in general, as sole products or mixtures with the corresponding pyrimidines
