Procedure

2-[4-(2-Aminoethoxy)phenyl]-1-ethyl-6-methoxy-1H-indole-3-carbonitrile (30 mg, 0.09 mmol), prepared as in example 1BB, step B, is dissolved in THF (400 μL), and Et3N (24 μL, 0.17 mmol). Acetyl chloride (10 μL, 0.14 mmol) is added, and the reaction mixture is stirred at room temperature for 2 h. The reaction mixture is partitioned between EtOAc and H2O. The organic layer is dried and concentrated. Purification by silica gel chromatography (EtOAc) yields N-{2-[4-(3-cyano-1-ethyl-6-methoxy-1H-indol-2-yl)phenoxy]ethyl}acetamide (33 mg, 97%) as a white solid.
