Reaction Steps
In a similar manner to Step 1 of Example 149, 4-hydroxy-7-[1-(tert-butoxycarbonyl)-5-(piperidinomethyl)indol-2-yl]isoindolinone (80.0 mg, 0.173 mmol) was dissolved in THF (4.0 mL), and the solution was treated with triphenylphosphine (136 mg, 0.519 mmol), 3-(tert-butyldimethylsilyloxy)propanol (0.111 mL, 0.519 mmol) and 40% DEAD-toluene solution (0.237 mL), followed by purification by preparative thin-layer chromatography (chloroform/methanol=4/1) to obtain 4-[3-(tert-butyldimethylsilyloxy)propoxy]-7-[1-(tert-butoxycarbonyl)-5-(piperidinomethyl)indol-2-yl]isoindolinone (58.6 mg, yield 53%).
