Conditions

Temperature
0 °C

Procedure

While vigorously stirring at 0° C., 5.00 g of 28% aqueous ammonia was added to 21.2 g of methyl acrylate. The resulting mixture was heated gradually to 25° C. over 20 hours. After concentration under reduced pressure, the residue was-purified by distillation under reduced pressure, whereby tris(2-methoxycarbonylethyl)amine was obtained (boiling point: 143° C./70 Pa, yield: 76%),
