実験手順

To a solution of 2-(4-aminophenyl)-1-cyclobutyl-6-hydroxy-1H-indole-3-carbonitrile (909 mg, 3 mmol) in pyridine (5 mL) is added 4-nitrophenyl chloroformate (6 mmol) at room temperature and then stirred for 2 h at room temperature. To the reaction is added cyclopropyl methyl carbinol and then stirred for 8 h at 80° C. The reaction mixture is diluted with 1N HCl and then extracted with ethyl acetate. The organic layer is concentrated and the residue is dissolved in EtOAc and triturated with hexane. The precipitate is collected by filtration and washed with hexane and dried in vacuo to afford [4-(3-cyano-1-cyclobutyl-6-hydroxy-1H-indol-2-yl)-phenyl]-carbamic acid 1-cyclopropyl-ethyl ester (996 mg, 80%).
