The reaction of tri(1-propenyl)amine with elemental sulfur in bipolar aprotic solvent (DMF, DMSO) at 50degreesC within 1.5 h furnished 5-methyl-2-ethylthiazole in 62% yield. 2H,5H-5-methyl-2-ethyl-thiazole, 2-hydroxy-5-methylbenzaldehyde were found among the side products. The formation paths of the compounds obtained are suggested.
