Reaction Steps

Ethylenediamine (0.828 mL, 12.38 mmol) is added to a solution of 4-isothiocyanatooxindole (0.471 g, 2.48 mmol) in methylene chloride (20 mL). The resulting solution is stirred at room temperature for 2.5 hours. The reaction mixture is concentrated by rotary evaporation to yield 0.688 g of crude 4-[N'-(2-aminoethyl)thioureido]oxindole as a green solid. This material is carried on directly to the next step.
