実験手順

To 4-nitrophenyl 3-(6,8-dichloro-2-methyl-1,2,3,4-tetrahydroisoquinolin-4-yl)phenylcarbamate (prepared by the procedure described in example 38) (200 mg, 0.40 mmol, 1.00 equiv, 95%) in DMF (5 mL) was added TEA (170 mg, 1.60 mmol, 4.00 equiv, 95%) and 2-(2-(2-(2-azidoethoxy)ethoxy)ethoxy)ethanamine (90 mg, 0.39 mmol, 1.00 equiv, 95%) and the resulting solution was stirred for 2 h. The mixture was then concentrated under vacuum, diluted with 10 mL of water and then extracted with 3×30 mL of ethyl acetate. The organic layers were combined, washed with 3×30 mL of brine, dried over anhydrous sodium sulfate and then evaporated. The residue was applied onto a silica gel column with ethyl acetate/petroleum ether (1:5˜1:1). This resulted in 160 mg (72%) of 1-(2-(2-(2-(2-azidoethoxy)ethoxy)ethoxy)ethyl)-3-(3-(6,8-dichloro-2-methyl-1,2,3,4-tetrahydroisoquinolin-4-yl)phenyl)urea as pale-yellow oil.
