To a solution of compound mixture, 6-(4-bromo-3-[1,3]dioxolan-2-yl-phenoxy)-2-chloro-nicotinonitrile and 2-(4-bromo-3-[1,3]dioxolan-2-yl-phenoxy)-6-chloro-nicotinonitrile, (4+5, 1 g, 2.6 mmol) in acetonitrile (anhydrous, 30 mL) was added 2-methylamino-ethanol (6, 2.1 mL, 26 mmol). The reaction was heated at 80° C. for 2 hours. After the reaction, all volatile components were evaporated in vacuo. Purification was accomplished by silica gel chromatography, eluting with 10%-80% EtOAc/hexanes gradient, affording 400 mg (36% yield) of the title compound.
