Versuchsvorschrift

To a solution of (Z)-5-amino-1,3-dihydro-4-(5-indolyl)-3-[(3-methoxy-1H-pyrrol-2-yl)methylene]-2H-indol-2-one (24 mg, 0.065 mmol) (from Step B above) in 2 mL tetrahydrofuran was added 2-thiopheneacetyl chloride (24 mg, 0.15 mmol) (Aldrich) and a saturated aqueous solution of sodium bicarbonate (0.15 mL). The reaction was stirred at room temperature for 14 hours at which time the reaction was diluted with water (10 mL), and the THF was evaporated in vacuo. The product was then extracted with EtOAc, and the combined organic layers were dried over magnesium sulfate and concentrated in vacuo. The resulting powder was recrystallized from EtOAc/Hex to give product as yellow crystals. (Yield 23 mg, 72%).
