Procedure

To a solution of 1-(5-methoxy-1H-indol-4-yl)-N,N-dimethylmethanamine (15 mg, 0.07 mmol; Intermediate 97) in DMF (1 mL) NaH (4 mg, 0.15 mmol) was added at rt. The reaction mixture was stirred at rt for 15 min and 5-methyl-1-benzothiophene-2-sulfonyl chloride (27 mg, 0.11 mmol) was added. The reaction mixture was allowed to stir at rt over night. The reaction was quenched by addition of water. Purification by preparative HPLC/UV (System B) afforded the title product (8 mg, 27%) as a white solid. MS (ESI+) for C21H22N2O3S2 m/z 415 (M+H)+.
