Reaction Steps

tert-Butyl 2-(5-amino-1H-indol-2-yl)-2-methylpropylcarbamate (58 mg, 0.19 mmol), 1-(benzo[d][1,3]dioxol-6-yl)cyclopropanecarboxylic acid (47 mg , 0.23 mmol), EDC (45 mg, 0.23 mmol), HOBt (31 mg, 0.23 mmol) and Et3N (80 μL, 0.57 mmol) were dissolved in DMF (4 mL) and stirred overnight at room temperature. The mixture was diluted with water and extracted with ethylacetate. The combined organic phases were dried over magnesium sulfate and evaporated to dryness. The residue was purified by silica gel chromatography (10-30% ethylacetate in hexane) to give tert-butyl 2-(5-(1-(benzo[d][1,3]dioxol-5-yl)cyclopropanecarboxamido)-1H-indol-2-yl)-2-methylpropyl-carbamate (88 mg, 94%). 1H NMR (400 MHz, CDCl3) δ 8.32(s, 1H), 7.62(d, J=1.5 Hz, 1H), 7.18-7.16(m, 2H), 7.02-6.94(m, 3H), 6.85(d, J=7.8 Hz, 1H), 6.19(d, J=1.5 Hz, 1H), 6.02(s, 2H), 4.54(m, 1H), 3.33 (d, J=6.2 Hz, 2H), 1.68(dd, J=3.7, 6.8 Hz, 2H), 1.36(s, 9H), 1.35(s, 6H), 1.09(dd, J=3.7, 6.8 Hz, 2H).
