摘要：
.beta.-Amino-acrylic acid esters of the formula(R.sup.1 R.sup.2)NCH.dbd.CR.sup.3 --COOR.sup.4can be obtained by reaction of .beta.-hydroxy-acrylic acid ester alkali metal salts of the formulaMe.sup..sym. .crclbar. OCH.dbd.CR.sup.3 --COOR.sup.4with ammonium salts of the formula(R.sup.1 R.sup.2) NH.sub.2.sup..sym. .crclbar.according to the general reaction equation(R.sup.1 R.sup.2) NH.sub.2 X+MeOCH.dbd.CR.sup.3 --COOR.sup.4 .fwdarw.(R.sup.1 R.sup.2) NCH.dbd.CR.sup.3 --COOR.sup.4 +MeX.dbd.H.sub.2 OR.sup.1, R.sup.2, R.sup.3, R.sup.4, Me.sup..sym. and X.sup..crclbar. having the meaning indicated in the description and the reaction being carried out in an aprotic organic solvent, in which the reaction components are suspended, as the reaction medium and it being possible to replace a part of the aprotic organic solvent by a protic organic solvent which is miscible with the aprotic solvent to give a homogeneous phase.
