反応手順

To a 50-mL 3-necked round-bottom flask was added 2-(2-(2-aminoethoxy)ethoxy)ethanamine (3.2 g, 21.59 mmol, 21.09 equiv) and dichloromethane (DCM; 20 mL). This was followed by the addition of a solution of 3-(6,8-dichloro-2-methyl-1,2,3,4-tetrahydroisoquinolin-4-yl)benzene-1-sulfonyl chloride (Intermediate 1.6) (400 mg, 1.02 mmol, 1.00 equiv) in DMF (5 mL) dropwise with stirring. The resulting solution was stirred for 5 h at which time it was diluted with 100 mL of ethyl acetate. The resulting mixture was washed successively with 2×10 mL of water and 1×10 mL of Brine. The organic layer was dried over anhydrous sodium sulfate and concentrated under vacuum. This resulted in 300 mg (58%) of N-(2-(2-(2-aminoethoxy)ethoxy)ethyl)-3-(6,8-dichloro-2-methyl-1,2,3,4-tetrahydroisoquinolin-4-yl)benzenesulfonamide as a yellow oil.
