反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: To a stirred yellow muddy mixture of 5-[2-oxo-1,2-dihydro-indol-(3Z)-ylidenemethyl]-2,4-dimethyl-1H-pyrrole-3-carboxylic acid (112.8 mg, 0.4 mmol), DMF (0.5 mL) and triethylamine (0.111 mL) in a 20 mL reaction tube, was added BOP reagent (265 mg). The mixture became clear in 5 min. 2-(2,6-dimethylpiperazin-1-yl)ethylamine (68.6 mg) (see., Tapia, L. Alonso-Cires, P. Lopez-Tudanca, R. Mosquera, L. Labeaga, A. Innerarity, A. Orjales, J. Med. Chem., 1999, 42, 2870-2880) was added into the clear mixture. The resulting solution was stirred at room temperature over night. Thin layer chromatography (10% methanol in methylene chloride) showed that all the starting material had been converted into the product. The reaction mixture was evaporated to dryness and then purified by flash chromatography (CH2Cl2/CH3OH=20/1−15/1) followed by recrystalization to give 5-[2-oxo-1,2-dihydro-indol-(3Z)-ylidenemethyl]-2,4-dimethyl-1H-pyrrole-3-carboxylic acid [2-(3,5-dimethylpiperazin-1-yl)ethyl)amide (83 mg, 50% yield). in a 20 mL reaction tube , 1999, 42, 2870-2880) was added into the clear mixture The reaction mixture was evaporated to dryness purified by flash chromatography (CH2Cl2/CH3OH=20/1−15/1) followed by recrystalization
