반응 단계
10.61 g of benzaldehyde (0.1 mol) and 11.31 g of ethyl cyanoacetate (0.1 mol) are placed in a flask equipped with a reflux condenser and heated to 90° C. 1.0 g of zeolite A (supplied by Merck: MS 3 Å) and 0.5 g of K2CO3 are then added in succession. The reaction starts immediately and is complete after about 4 minutes. The reaction mixture is filtered while still hot, giving ethyl cyanocinnamate in a purity of >96%. The yield is 98%.
