Reaction Steps

To a solution of (6-chloro-4-pyrrolidin-1-yl-pyridin-2-yl)-(4-trifluoromethoxy-phenyl)-amine (120 mg, 0.336 mmol) in 1,4-dioxane (8 mL) was added potassium-tert-butoxide (75 mg, 0.670 mmol) and tetrakis(triphenylphosphine)palladium (0) (20 mg, 0.017 mmol), followed by phenyl boronic acid (102 mg, 0.836 mmol). The resulting reaction mixture was refluxed for 10 hours, after which time water was added 100 mL to the reaction mixture, and the product was extracted with ethyl acetate (100 mL×3). The organic layer was dried over sodium sulphate, filtered, and the filtrate was concentrated under vacuum. The resulting product was purified by column chromatography using 230-400 mesh silica gel (20:80 acetone:petroleum ether) to afford the desired compound (75 mg, purity 99%, yield 6%.).
