Procedure

Add 2-bromopropionyl chloride to a solution of (indol-7-yl)methylamine and triethylamine (0.49 g, 47.6 mmol) in tetrahydrofuran (20 ml) at 0° C. 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 to provide the desired compound (0.62 g, 46%) as a yellow solid.
