Procedure
Add 2-bromopropionyl chloride (3.25 g, 18.96 mmol) to a solution of N-[(indol-7-yl)methyl]-2,4-dimethoxybenzylamine (5.0 g, 17.24 mmol) and triethylamine (3.49 g, 64.48 mmol) in tetrahydrofuran (100 ml). Stir for 1 hour at room temperature and quench with saturated aqueous sodium bicarbonate. Extract with ethyl acetate, concentrate under reduced pressure, and subject the residue to silica gel chromatography eluting with 1:1 ethyl acetate:hexanes to provide the desired compound (4.72 g, 63%).
