Procedure

A suspension of ethenesulfonic acid [4-(3-cyano-1-ethyl-6-methoxy-1H-indol-2-yl)-phenyl]amide, prepared above, (70 mg, 0.18 mmol), morpholine (0.05 mL, 0.55 mmol) in CH3CN (1.5 mL) is heated at reflux for 1.5 h. After cooling to room temperature, the reaction is concentrated and the residue is purified by flash chromatography (acetone/EtOAc, 2/98) over silica gel to afford 89 mg (100%) of 2-morpholin-4-yl-ethanesulfonic acid [4-(3-cyano-1-ethyl-6-methoxy-1H-indol-2-yl)-phenyl]amide as a tan foam.
