実験手順

Into a 10-mL round-bottom flask purged and maintained with an inert atmosphere of nitrogen, was placed a solution of 4-(3-bromophenyl)-6,8-dichloro-2-methyl-1,2,3,4-tetrahydroisoquinoline (intermediate 1.4) (400 mg, 1.08 mmol, 1.00 equiv) in DMSO (6 mL), 2-(2-(2-(2-azidoethoxy)ethoxy)ethoxy)ethanamine (236.11 mg, 1.08 mmol, 1.00 equiv), (S)-pyrrolidine-2-carboxylic acid (24.79 mg, 0.21 mmol, 0.20 equiv), copper(I) iodide (20.48 mg, 0.11 mmol, 0.10 equiv) and potassium carbonate (223.18 mg, 1.62 mmol, 1.50 equiv). The resulting solution was stirred at 90° C. in an oil bath and the reaction progress was monitored by LCMS. After stirring overnight the reaction mixture was cooled with a water/ice bath and then diluted with ice water. The resulting solution was extracted with 3×30 mL of ethyl acetate and the organic extracts were combined and washed with 2×20 mL of brine. The mixture was dried over anhydrous sodium sulfate and concentrated under vacuum. The residue was applied onto a silica gel column with ethyl acetate/petroleum ether (2:1). This resulted in 130 mg (24%) of N-(2-(2-(2-(2-azidoethoxy)ethoxy)ethoxy)ethyl)-3-(6,8-dichloro-2-methyl-1,2,3,4-tetrahydroisoquinolin-4-yl)benzenamine as yellow oil.
