Reaktionsschritte

4-[2-(4-Hydrazino-6-(morpholin-4-yl)-pyrimidin-2-yloxy)-ethyl]-morpholine (80 mg; ¼ mmol) was added to a flask along with 5-methylisatin (53 mg; ⅓ mmol) and ethanol (4 mL). One drop of acetic acid was added, and the reaction was stirred overnight at 60° C. The mixture was then filtered and the precipitate was washed with ethanol (1 mL) and dried to give 5-methyl-3-{[6-morpholin-4-yl-2-(2-morpholin-4-yl-ethoxy)-pyrimidin-4-yl]-hydrazono)}-1,3-dihydro-indol-2-one.
