General description

2-Ethyl-4-methylthiazole is a thiazole derivative. It is reported to be one of the aromatic volatile compound formed during the Maillard reaction between reaction L-ascorbic acid and L-cysteine. Its palladium-catalyzed direct coupling reaction with 3-bromochromen-4-one has been examined.

Application

2-Ethyl-4-methylthiazole may be used in the synthesis of the following:
  • 4-(2-ethyl-4-methylthiazol-5-yl)benzaldehyde
  • 2-(2-ethyl-4-methylthiazol-5-yl)benzonitrile
  • 4-(2-ethyl-4-methylthiazol-5-yl)-pyridine
