Procedure
To a mixture of 2-chloro-6-hydrazinopyridine (2.00 g, 13.93 mmol) and ethyl-2-cyano-3-ethoxyacrylate (2.36 g, 13.93 mmol) was added EtOH (14 mL) and the resulting suspension was stirred at room temperature. After 5 min, the mixture was heated at reflux. After 2 h, the reaction mixture was allowed to cool to room temperature. The title compound was isolated as a white solid by filtration, and was used without further purification: LCMS m/z 267.0 [M+I-1]+.
