Procedure
To a solution of 1-(benzo[d][1,3]dioxol-5-yl)cyclopropanecarboxylic acid (0.075 g, 0.36 mmol) in acetonitrile (1.5 mL) were added HBTU (0.138 g, 0.36 mmol) and Et3N (152 μL, 1.09 mmol) at room temperature. The mixture was stirred at room temperature for 10 minutes before a solution of 2-(5-amino-1H-indol-2-yl)-2-methylpropan-1-ol (0.074 g, 0.36 mmol) in acetonitrile (1.94 mL) was added. After addition, the reaction mixture was stirred at room temperature for 3 h. The solvent was evaporated under reduced pressure and the residue was dissolved in dichloromethane. The organic layer was washed with 1 N HCl (1×3 mL) and saturated aqueous NaHCO3 (1×3 mL). The organic layer was dried over Na2SO4, filtered and evaporated under reduced pressure. The crude material was purified by column chromatography on silica gel (ethyl acetate/hexane=1/1) to give 1-(benzo[d][1,3]dioxol-5-yl)-N-(2-(1-hydroxy-2-methylpropan-2-yl)-1H-indol-5-yl)cyclopropanecarboxamide (0.11 g, 75%). 1H NMR (400 MHz, DMSO-d6) δ 10.64 (s, 1H), 8.38 (s, 1H), 7.55 (s, 1H), 7.15 (d, J=8.6 Hz, 1H), 7.04-6.90 (m, 411), 6.06 (s, 1H), 6.03 (s, 2H), 4.79 (t, J=2.7 Hz, 1H), 3.46 (d, J=0.0 Hz, 2H), 1.41-1.39 (m, 2H), 1.26 (s, 6H), 1.05-1.02 (m, 2H).
