An easy general synthesis of 2-(N,N-dialkylamino)thiazol-5-yl aldehydes and ketones
Abstract
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.
