Reaction Steps

To a solution of 4-(2-aminoethyl)benzenesulfonamide (2.00 g, 10 mmol), 3-bromoprop-1-yne (2.16 mL, 20 mmol, 80% in toluene) in acetonitrile (50 mL) was added DIPEA (3.0 mL). The reaction mixtures were stirred at room temperature for overnight and concentrated under reduced pressure to give a residue. The residue was purified by biotage over silica gel eluting with DCM to 10% MeOH in DCM to afford 4-(2-(di(prop-2-yn-1-yl)amino)ethyl)benzenesulfonamide as a yellow oil (2.40 g, 87%), MS (ESI), 277.1 (M+H)+.
