Reaction between 2-chloro-5-thiazolyl-lithium and N,N-dialkylformamides or amides gave 2-N,N-dialkylaminothiazol-5-yl aldehydes or ketones on quenching with water.Quenching with acid gave 2-chlorothiazole-5-yl aldehydes or ketones, from which chloride was easily displaced by free amines.
N,N-Disubstituted 2-Aminothiazole-5-carbaldehydes: Preparation and Investigation of Structural Features
Gillon, David W.,Forrest, Ian J.,Meakins, G. Denis,Tirel, Malcolm D.,Wallis, John D.
, p. 341 - 348 (2007/10/02)
Methods of preparing N,N-disubstituted 2-aminothiazoles have been investigated. 4-Substituted N,N-dimethyl-, N-benzyl-N-methyl-, and N-methyl-N-phenyl-amines were prepared and converted by Vilsmeier formylation into 2-amino-5-carbaldehydes which were examined by i.r. and 1H n.m.r. spectrometry.The aldehyde group adopts the carbonyl O,S-syn-conformation.With the N,N-dimethyl and N-benzyl-N-methyl compounds the barrier to rotation of the amine group (ΔG(excit.)) is 50-55 kJ mol-1 and is insensitive to the nature of the 4-substituent.The amine group of the N-methyl-N-phenyl compounds has a marked preference for one orientation.This was shown by a crystallographic study of 4-t-butyl-2-(N-methyl-N-phenylamino)thiazole-5-carbaldehyde to have the phenyl group directed towards the sulphur atom of the thiazole ring.
