실험 절차

In a similar manner to Step 1 of Example 149, 4-hydroxy-7-[1-(tert-butoxycarbonyl)-5-(piperidinomethyl)indol-2-yl]isoindolinone (0.0817 g, 0.177 mmol) was dissolved in THF (4.0 mL), and the solution was treated with triphenylphosphine (0.0930 g, 0.354 mmol), 40% DEAD-toluene solution (0.161 mL, 0.354 mmol) and 1-(3-hydroxypropyl)-4-methylpiperazine (0.140 g, 0.855 mmol), followed by purification by flash column chromatography (chloroform/methanol=7/3) to obtain 4-[3-(4-methylpiperazin-1-yl)propoxy]-7-[1-(tert-butoxycarbonyl)-5-(piperidinomethyl)indol-2-yl]isoindolinone (0.0617 g, yield 58%).
