HCID 708720803-(2-(2-(2-aminoethoxy)ethoxy)ethoxy)-N-(3-(6,8-dichloro-2-methyl-1,2,3,4-tetrahydroisoquinolin-4-yl)phenyl)propanamide

Versuchsvorschrift

Into a 100-mL round-bottom flask, was placed N-(3-(6,8-dichloro-2-methyl-1,2,3,4-tetrahydroisoquinolin-4-yl)phenyl)-3-(2-(2-(2-(1,3-dioxoisoindolin-2-yl)ethoxy)ethoxy)ethoxy)propanamide (870.0 mg, 1.36 mmol, 1.00 equiv) and 1M hydrazine monohydrate in ethanol (30.0 mL, 30.0 mmol). The resulting solution was heated at reflux for 1 hour. The resulting mixture was cooled to room temperature and concentrated under vacuum. The residual solution was diluted with 30 mL of water and then extracted with 3×50 mL of DCM. The combined organic layers were washed with brine, dried over anhydrous sodium sulfate and concentrated under vacuum. The residue was applied onto a silica gel column with DCM/methanol (100˜50:1˜10:1˜1:1). This resulted in 600 mg (85%) of 3-(2-(2-(2-aminoethoxy)ethoxy)ethoxy)-N-(3-(6,8-dichloro-2-methyl-1,2,3,4-tetrahydroisoquinolin-4-yl)phenyl)propanamide as a pale yellow syrup.
