Reaction Steps

Benzenesulfonic acid (158.51 mg) was added to a solution of N-[2-(diethylamino)ethyl]-N-(2-{[2-(4-hydroxy-2-oxo-2,3-dihydro-1,3-benzothiazol-7-yl)ethyl]amino}ethyl)-3-[2-(1-naphthyl)ethoxy]propanamide (0.58 g) in methanol (5.8 mL) producing an clear solution. The mixture was stirred at room temperature for 1 h. The title compound was obtained as an amorphous solid after evaporation to dryness.
