Reaction Steps

(6-Bromo-quinolin-2-yl)-(5-methyl-furan-2-ylmethyl)-amine (prepared from 6-bromo-2-chloroquinoline and 5-methyl-2-furanmethanamine as described in example 43, step A, 200 mg, 0.631 mmol) was dissolved in 5 mL dioxane. Argon was bubbled through the solution for 2 minutes to remove oxygen. Benzamide (107 mg, 0.884 mmol), cesium carbonate (308 mg, 0.948 mmol) bis(dibenzylideneacetone)palladium (29 mg, 0.032 mmol) and 4,5-bis(diphenylphosphino)-9,9-dimethylxanthene (55 mg, 0.095 mmol) were added. The reaction mixture was stirred in a sealed tube at 100° C. for 16 h. The solvent was evaporated and the residue purified by flash chromatography on silica gel (heptane/ethyl acetate 100:0->60:40 gradient). The title compound was obtained as a white solid (110 mg, 49%), MS: m/e=358.3 (M+H+).
