Reaction Steps
A mixture of [4-(4-chlorophenyl)-2,2-dimethyl-2H-chromen-7-yl]trifluoromethanesulfonate (100 mg), mesylamine (27 mg), cesium carbonate (117 mg), tris(dibenzylideneacetone)dipalladium(10 mg, 10% wt), 9,9-dimethyl-4,5-bis(diphenylphosphino)-9H-xanthen (Xantphos, 20 mg, 20% wt) and dioxane (2 mL) was heated under reflux for 10 hours. The reaction mixture was filtered, the filtrate was concentrated in vacuo, and the residue was purified by column chromatography on silica gel (petroleum ether/ethyl acetate=100/1) to give the titled compound (50 mg) as a colorless powder.
