Versuchsvorschrift

To a stirred solution of 4-[3-(4-aminophenyl)-1-ethyl-1H-pyrazol-4-yl]-2-[3-(dimethylaminomethyl)phenyl]-1H-pyrrolo[2,3-b]pyridine (1.0 mmol) in tetrahydrofuran (15 mL) was added p-nitrophenylchloroformate (1.1 mmol). After stirring for 1 h at room temperature a solution of 2.0 M dimethylamine in tetrahydrofuran (14 mmol) was added. The reaction was stirred an additional 1 h at room temperature then concentrated under vacuum. The residue which remained was triturated with aqueous sodium hydroxide, filtered, washed with cold water, and dried under vacuum. Purification by Gilson reverse phase HPLC afforded title compound as an off-white solid (46%). ESMS (M+H)+: 508.4
