Reaction Steps
To an aqueous solution containing 14.20 g of sodium hydroxide and 33.75 g of methyl cyanoacetate, 30.32 g of 3,4-(methylenedioxy)benzaldehyde was added, followed by stirring at 95° C. for 16 hours. After completion of the reaction, an aqueous diluted hydrochloric acid solution was added to obtain a pale yellow solid. The resultant solid was recrystallized from ethanol to obtain a crystal having a melting point of 233° C.
