An unexpected outcome of a general thiazole synthesis
Abstract
The reaction between N-benzoyl-N′-methyl-N′-phenylthiourea and chloroacetone gives 5-benzoyl-4-methyl-2-(N-methyl-N-phenylamino)thiazole rather than the 5-acetyl-4-phenylisomer which would be predicted from previous work on this route to thiazoles.
