Versuchsvorschrift

To a mixture of 1-(2,2-difluorobenzo[d][1,3]dioxol-5-yl)cyclopropanecarboxylic acid (346 mg, 1.4 mmol), 6-fluoro-1,1-dimethyl-2,3-dihydro-1H-pyrrolo[1,2-a]indol-7-amine (260 mg, 1.2 mmol) and HATU (543 mg, 1.4 mmol) in DMF (5 mL) was added triethylamine (0.40 mL, 2.9 mmol). The reaction was stirred at room temperature overnight and then partitioned between ethyl acetate and water. The aqueous layer was extracted with ethyl acetate and the combined organic layers were washed with brine and dried over MgSO4. After the removal of solvent, the residue was purified by column chromatography (10-20% ethyl acetate-hexanes) to afford 1-(2,2-difluorobenzo[d][1,3]dioxol-5-yl)-N-(6-fluoro-1,1-dimethyl-2,3-dihydro-1H-pyrrolo[1,2-a]indol-7-yl)cyclopropanecarboxamide (342 mg, 65%).
