Participants

Reaction Steps

3-Dimethylamino-1-(2-ethylamino-4-methyl-thiazol-5-yl)-propenone was prepared by reaction between 1-(2-ethylamino-4-methyl-thiazol-5-yl)-ethanone and 3-chloro-pentane-2,4-dione. It was then condensed with N-(3-nitro-phenyl)-guanidine nitrate in the usual manner to afford the title compound.
