A vial was charged with (E)-ethyl 3-(6-chloro-4-(methylamino)pyridin-3-yl)acrylate (45 mg), 70% aqueous ethyl amine (1 mL) and NMP (1 mL). The vial was sealed and heated with microwave irradiation for 35 min at 150° C. Aqueous sodium bicarbonate solution was added and the mixture was extracted with dichloromethane. The combined organic extracts were dried over sodium sulfate, filtered, and concentrated. The residue was chromatographed on silica gel (50% ethyl acetate in hexanes eluant) to provide the title compound. MS (m/z) 204.0 (M+1).
