Reaction Steps

A 25 mL round-bottomed flask is charged with 4-(2,6-difluorophenoxy)-6-(4-methylthiazol-2-ylamino)nicotinaldehyde (534 mg, 1.54 mmol) and THF (10 mL). Methyl(triphenylphosphoranylidene)acetate (668 mg, 2.00 mmol) is added and the reaction mixture is stirred at room temperature. After 4 hours, additional methyl(triphenylphosphoranylidene)acetate (668 mg, 2.00 mmol) is added and the reaction mixture is and stirred overnight. The precipitate is filtered, concentrated, and purified by silica gel chromatography (1:1 EtOAc in hexanes) to afford (E)-methyl 3-(4-(2,6-difluorophenoxy)-6-(4-methylthiazol-2-ylamino)pyridin-3-yl)acrylate.
