实验步骤: 26.2 g (0.128 mol) of dimethyl benzylidenemalonate and 20.1 g (0.128 mol) of ethyl-3-amino-hex-2-en-oate are stirred at 140° C. for 3 days with a spatula tip full of sodium ethoxide. The mixture is chromatographed on silica gel using methylene chloride and crystallised from petroleum ether. The mixture is chromatographed on silica gel crystallised from petroleum ether
