Procedure

2-[4-(2-bromoethoxy)-phenyl]-1-ethyl-6-methoxy-1H-indole-3-carbonitrile (40 mg, 0.1 mmol), prepared as in step A above, is combined with morpholine (50 μL, 0.58 mmol) and acetonitrile (1.0 mL). This is heated at 85° C. for 2 h. The reaction mixture is then partitioned between CH2Cl2 and H2O. The organic layer is dried and concentrated. Purification by silica gel chromatography (6/4, acetone/hexanes) yields 1-ethyl-6-methoxy-2-[4-(2-morpholin-4-yl-ethoxy)-phenyl]-1H-indole-3-carbonitrile (39 mg, 96%) as a white solid.
