実験手順

To 3-dimethylaminomethyl-pyrrolo[2,3-b]pyridine-1-carboxylic acid tert-butyl ester (511, 2.60 g, 9.44 mmol) in toluene (50.00 mL) was added isopropyl chloroformate (11.3 mL, 1.0 M in toluene) under an atmosphere of nitrogen. The reaction was stirred at room temperature for 3 hours. The reaction was poured into water and extracted with ethyl acetate. The organic layer was dried over anhydrous sodium sulfate and filtered. The filtrate was concentrated and purified by silica gel column chromatography eluting with 20% ethyl acetate in hexane to give a white solid (512, 2.0 g, 79.4%).
