N,N-Disubstituted 2-aminothiazoles were prepared and converted into the corresponding 5-carboxaldehydes by Vilsmeier formylation. The aldehydes were studied by IR and 1H NMR spectroscopy. The aldehyde group adopts the carbonyl O,S-syn conformation. With N,N-di-Me and N-benzyl-N-Me compounds the barrier to rotation of the amine group is 50-55 kJ/mol and is insensitive to the nature of the 4-substituent. The amine group of the N-methyl-N-Ph compounds has a marked preference for one orientation. Thus, x-ray crystallog. anal. of triazole I showed the Ph group to be directed towards the S of the thiazole ring. The results of the phys. methods overlap in establishing the importance of a mesomeric interaction between the functional groups of 2-aminothiazole-5-carboxaldehydes.
