Procedure

1-(2,2-difluorobenzo[d][1,3]dioxol-5-yl)cyclopropanecarbonyl chloride (26 mg, 0.1 mmol) was added to a solution of 5-amino-2-tert-butyl-1H-indole-4-carbonitrile (21 mg, 0.1 mmol) and triethylamine (41.7 μL, 0.3 mmol) in DMF (1 mL). The reaction was stirred at room temperature overnight, then filtered and purified by reverse-phase HPLC to yield the product, N-(2-tert-butyl-4-cyano-1H-indol-5-yl)-1-(2,2-difluorobenzo[d][1,3]dioxol-5-yl)cyclopropanecarboxamide. ESI-MS m/z calc. 437.2, found 438.7 (M+1)+. Retention time 2.10 minutes. 1H NMR (400 MHz, DMSO-d6) δ 11.48 (s, 1H), 8.88 (s, 1H), 7.52 (d, J=8.5 Hz, 2H), 7.41 (d, J=8.3 Hz, 1H), 7.32 (dd, J=1.5, 8.3 Hz, 1H), 7.03 (d, J=8.6 Hz, 1H), 6.21 (d, J=1.8 Hz, 1H), 1.51-1.49 (m, 2H), 1.36 (s, 9H), 1.18-1.16 (m, 2H).
