N′-Thioaroyl-N,N-dimethylformamidines undergo exchange of sulphur for oxygen on treatment with benzonitrile oxide, are hydrolysed to thioamides by ammonia, hydrazine and hydroxylamine, undergo S-methylation on treatment with methyl iodide, and react with α-bromoketones and ketenes to give 5-aroylthiazoles and 6-oxo-6H-1,3-thiazines respectively.
N'-硫代芳酰基-N,N-二甲基甲am在用苄腈氧化物处理时被硫交换为氧,被氨,肼和羟胺水解为硫代酰胺,在甲基碘处理后进行S-甲基化,并与α-溴代酮和烯酮分别得到5-芳酰基噻唑和6-氧代-6 H -1,3-噻嗪。

The preparation of 4- and 5-acyl- and aroyl-2-substituted aminothiazoles is described. The condensation of thioureas with acyl halides leading to 4,5-disubstituted-2-aminothiazoles and 7-(4H)benzothiazolones is discussed. A discussion of the isolation of various intermediates and the mechanistic pathway is also included. A number of 2-anilino or 2-benzyl-4- or 5-aroylthiazoles possessed moderate oral
