Procedure
2-Formylcycloheptanone (1.70 g, 12.1 mmol) and ethyl 3-aminocrotonate (1.58 g, 12.1 mmol) were stirred at 100° C. for 15 hours. After cooling, the reaction solution was purified by a silica gel column chromatography (ether/hexane=1:3) to obtain the title compound (1.35 g, 46.1%) as pale yellow powder.
