Procedure
{(4-[3-(2-formyl-4,5,6,7-tetrahydro-1H-indol-3-yl)-propyl]-piperazin-1-yl}-acetic acid ethyl ester (60 mg, 0.1 73 mmol) was condensed with 5-methylaminosulfonyloxindole (45 mg, 0.1 9 mmol, 1.1 eq.) following the procedure used in Example 1 above. The reaction mixture was purified by flash chromatography (dichloromethane/methanol 10/1) to give the desired product.
