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