실험 절차

In a similar manner to Step 2 of Example 6, 4-chloro-7-[1-(tert-butoxycarbonyl)-5-formylindol-2-yl]isoindolinone (36.2 mg, 0.0881 mmol) was dissolved in acetonitrile (2 mL), and the solution was treated with piperidine (0.035 mL, 0.35 mmol), acetic acid (0.101 mL, 1.76 mmol) and sodium triacetoxyborohydride (93 mg, 0.44 mmol), followed by purification by preparative thin-layer chromatography (hexane/ethyl acetate=1/2) to obtain 4-chloro-7-[1-(tert-butoxycarbonyl)-5-(piperidinomethyl)indol-2-yl]isoindolinone (31.2 mg, yield 74%).
