反応手順
In a similar manner to Step 2 of Example 161, 4-trifluoromethanesulfonyloxy-7-[1-(tert-butoxycarbonyl)-5-(piperidinomethyl)indol-2-yl]isoindolinone (60.0 mg, 0.101 mmol) was dissolved in diethylamine (3.0 mL), and the solution was treated with bis(triphenylphosphine)dichloropalladium (8.6 mg, 0.012 mmol), copper iodide (6.9 mg, 0.036 mmol), propargyl alcohol (0.029 mL, 0.51 mmol), followed by purification by preparative thin-layer chromatography (chloroform/methanol=5/1) to obtain 4-(3-hydroxy-1-propinyl)-7-[1-(tert-butoxycarbonyl)-5-(piperidinomethyl)indol-2-yl]isoindolinone (18.8 mg, yield 37%).
