참여 물질

반응 단계

A mixture of benzaldehyde (63.67 g; 600 mmol), methyl acrylate (60 ml; 667 mmol) and 1,4-diazabicyclo [2.2.2] octane (13.46 g; 120 mmol) is stirred at ambient temperature for 119 hours. To the reaction solution is added water (60 ml), 37% hydrochloric acid (60 ml) and ethyl acetate (120 ml), and then, the organic phase is extracted. The resulting organic phase is washed twice with saturated saline (60 ml), dried over anhydrous sodium sulfate and filtered, then concentrated under reduced pressure, to give a crude product of the title compound at a yield of 108.8 g.
