Conditions

Temperature: 110 °C

Procedure

N-(2-tert-butyl-1-(2-chloroethyl)indolin-5-yl)-1-(2,2-difluorobenzo[d][1,3]dioxol-5-yl)cyclopropanecarboxamide (51 mg), NaCN (16 mg, 0.32 mmol) and KI (cat) in EtOH (0.6 mL) and water (0.3 mL) were combined and heated at 110° C. for 30 min in the microwave. The solvent was removed under reduced pressure and the residue was purified by column chromatography on silica gel (2-15% ethyl acetate/hexanes) providing N-(2-tert-butyl-1-(2-cyanoethyl)indolin-5-yl)-1-(2,2-difluorobenzo[d][1,3]dioxol-5-yl)cyclopropanecarboxamide (24 mg, 48%).
