Versuchsvorschrift
To 831 mg of 4-acetylbenzoic acid p-nitrophenyl ester, 788 mg of 2-amino-4-[(2-diisopropylaminoethyl)aminocarbonyl]-1,3-thiazole were added. The resulting mixture was stirred at 130° C. for 8 hours. The reaction mixture was purified by column chromatography on NH silica gel (chloroform), whereby 693 mg of 2-[N-(4-acetylbenzoyl)amino]-4-[(2-diisopropylaminoethyl)aminocarbonyl]-1,3-thiazole were obtained. After 2 ml of a 4N hydrochloric acid--dioxane solution were added to the resulting compound, the solvent was distilled off under reduced pressure. The residue was recrystallized from a mixed solvent of isopropyl ether and ethanol, whereby 395 mg of the title compound were obtained as yellow powder.
