A process for preparing an amidinecarboxylic acid which comprises reacting, in water, an alkoxyiminoacetic acid ester represented by the formula ##STR1## (wherein R.sup.1 and R.sup.2 individually represent an alkyl group of 1 to 4 carbon atoms) with an amine represented by the formula R.sup.3 --NH.sub.2 (wherein R.sup.3 represents a hydrogen atom, an alkyl group of 1 to 4 carbon atoms, an alkenyl group of 2 to 4 carbon atoms, a cycloalkyl group of 5 to 7 carbon atoms or a benzyl group).
一种制备酰胺基羧酸的方法,包括在水中反应一个由下式表示的烷氧基亚氨基乙酸酯:##STR1##(其中R1和R2分别表示1至4个碳原子的烷基),与一个由下式表示的胺反应:R3-NH2(其中R3表示氢原子,1至4个碳原子的烷基,2至4个碳原子的烯基,5至7个碳原子的环烷基或苄基)。
