실험 절차
To a solution of 2-methyl-3-methylenesuccinic acid dimethyl ester (9.81 g) in toluene (100 ml) was added 2,4-dimethoxybenzylamine (9.72 g) and the mixture was stirred for 3 days at reflux. This reaction solution was cooled to room temperature and then purified by silica gel column chromatography (eluent: n-hexane/chloroform=1/1 to 0/1) to give the titled compound (14.2 g).
