実験手順

To a mixture of 1-(2,2-difluorobenzo[d][1,3]dioxol-5-yl)cyclopropanecarboxylic acid (183 mg, 0.75 mmol), (R)-3-(5-amino-1-((2,2-dimethyl-1,3-dioxolan-4-yl)methyl)-6-fluoro-1H-indol-2-yl)-3-methylbutan-1-ol containing some 3-(5-amino-6-fluoro-1H-indol-2-yl)-3-methylbutan-1-ol (220 mg, 0.63 mmol) and HATU (287 mg, 0.75 mmol) in DMF (3.0 mL) was added triethylamine (0.21 mL, 1.5 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 (20-40% ethyl acetate-hexanes) to afford (R)-1-(2,2-difluorobenzo[d][1,3]dioxol-5-yl)-N-(1-((2,2-dimethyl-1,3-dioxolan-4-yl)methyl)-6-fluoro-2-(4-hydroxy-2-methylbutan-2-yl)-1H-indol-5-yl)cyclopropanecarboxamide (315 mg, 87%, contains some 1-(2,2-difluorobenzo[d][1,3]dioxol-5-yl)-N-(6-fluoro-2-(4-hydroxy-2-methylbutan-2-yl)-1H-indol-5-yl)cyclopropanecarboxamide). ESI-MS m/z calc. 574.2 found 575.7 (M+1)+. Retention time 2.08 minutes.
