Reaction Steps
A mixture of ethyl 7-bromo-3-(3-(naphthalen-1-yloxy)propyl)-1H-indole-2-carboxylate (EXAMPLE 1C) (45.2 mg), 3-aminobenzonitrile (14.2 mg), 2′-(dicyclohexylphosphino)-N,N-dimethylbiphenyl-2-amine (Cy-map) (5.9 mg), tris(dibenzylideneacetone)dipalladium(0) (4.6 mg), and Cs2CO3 (46 mg) in dioxane (1 mL) was degassed via vacuum-nitrogen cycle three times. The reaction mixture was heated at 100° C. for 16 hours. The reaction mixture was partitioned between water and ethyl acetate. The organic layer was separated, and the aqueous layer was extracted with additional ethyl acetate. The combined organic layers were washed with brine, dried over MgSO4, filtered, and concentrated in vacuo. The residue was purified with flash chromatography (1:9 EtOAc/Hex) to provide the title compound.
