A novel method is introduced on the synthesis of methyl 3-aminocrotonate by methyl aceto- acetate with ammonium carbamate. The yield rate is 95.43%. The feed ratio,distillation and raw materials take effect on reaction and product purity. The subsequent distillation recycles solvents, and restores the by-product ammonium hydrogen carbonate during reaction. This method enjoys shorter reaction time,no pollution, easy separation, high yield and good purity.
