To a solution of N1-(3-aminopropyl)-N1-methylpropane-1,3-diamine (560 mg, 3.85 mmol) dissolved in DCM (20 mL), was added triethylamine (300 mg, 2.96 mmol) and 3-(6,8-dichloro-2-methyl-1,2,3,4-tetrahydroisoquinolin-4-yl)benzene-1-sulfonyl chloride (300 mg, 0.77 mmol). The resulting solution was stirred for 3 h at room temperature. After removing the solvent, the resulting residue was diluted with EtOAc (50 mL), washed with water (2×10 mL) and dried over anhydrous sodium sulfate. The crude product was purified by Flash-Prep-HPLC with H2O:MeOH (1:4) to afford 300 mg (74%) of N-(3-((3-aminopropyl)(methyl)amino)propyl)-3-(6,8-dichloro-2-methyl-1,2,3,4-tetrahydroisoquinolin-4-yl)benzenesulfonamide as a yellow oil.
