Procedure

To a solution of 2 g of 5-aminoindole in 125 mL of anhydrous acetone is added dropwise 1.25 g of 2-chloroethyl isocyanate. This solution was stirred for 16 h at room temperature, cooled at °20° C., and filtered. The solvent is evaporated and the residue was crystallized from methanol and washed with ether to give a brownish solid, yield 30%, mp 159°-161° C.
