実験手順

Into a 50-mL 3-necked round-bottom flask purged and maintained with an inert atmosphere of nitrogen, was placed a solution of 3-(6,8-dichloro-2-methyl-1,2,3,4-tetrahydroisoquinolin-4-yl)benzene-1-sulfonyl chloride (intermediate 1.6) (100 mg, 0.26 mmol, 1.00 equiv) in DCM (5 mL). This was followed by the addition of a solution of ethane-1,2-diamine (307 mg, 5.11 mmol, 19.96 equiv) in DCM/DMF (10/1 mL). The resulting solution was stirred for 5 h at room temperature. The mixture was concentrated under vacuum. The resulting solution was diluted with 50 mL of ethyl acetate and washed with 2×10 mL of water and then 1×10 mL of Brine. The organic layer was dried over anhydrous sodium sulfate and concentrated under vacuum to afford 90 mg (76%) of N-(2-aminoethyl)-3-(6,8-dichloro-2-methyl-1,2,3,4-tetrahydroisoquinolin-4-yl)benzenesulfonamide as yellow oil.
