2-Amino-4-(1-methylindol-3-yl)thiazole (11c) has a characteristic nucleophilic nature at the 5-position and add to the 4-position of acetylpyridinium acetate (13) producing 2-acetylamino-5-(1-acetyl-1,4-dihydropyridin-4-yl)-4-(1-methylindol-3-yl) thiazole (1c). Its structure was established by X-ray single crystallographic analysis. Applying the results, simple syntheses of the related tris- (1a-b and 2-8) and tetrakis-linked heterocycles (9) were achieved.
