실험 절차

A mixture of 320 mg of 2-benzo[1,3]dioxol-5-ylmethyl-1-tert-butoxycarbonylpiperazine as synthesized in the above step, 200 mg of 1-chloro-7-methoxyisoquinoline and 100 mg of triethylamine was stirred in 2 ml of ethylene glycol at 150° C. for 18 hours. After addition of water, the solution was extracted with ethyl acetate, dried over anhydrous magnesium sulfate, and the solvent was distilled off under reduced pressure. The residue was purified on silica gel column chromatography (ethyl acetate:n-hexane=1:1) to provide 210 mg (44%) of 1-(2-benzo[1,3]dioxol-5-ylmethyl-1-tert-butoxycarbonylpiperazin-4-yl)-7-methoxyisoquinoline.
