실험 절차

2-(2-(2-(2-azidoethoxy)ethoxy)ethoxy)ethyl methanesulphonate (175 mg, 0.58 mmol) and Cs2CO3 (190 mg, 0.58 mmol) are added to the mixture of 3-(4-hydroxyphenyl)-7-methoxyisoquinolin-1(2H)-one (compound 45) (130 mg, 0.48 mmol) in DMF (6 mL). The reaction mixture is heated at 80° C. for 24 hours. Then the solvent is evaporated off, the reaction crude is added to water (100 mL) and extracted with CH2Cl2 (3×100 mL). The organic phase is dried over MgSO4, filtered and concentrated under reduced pressure. The residue obtained is purified by silica column chromatography using a gradient of EtOH (1 to 3%) in CH2Cl2 as eluents. Intermediate 3-(4-(2-(2-(2-(2-azidoethoxy)ethoxy)ethoxy)ethoxy)phenyl)-7-methoxyisoquinolin-1(2H)-one (52 mg, 23%) is obtained, which is used directly in the following stage.
