다음 일반식(Ⅱ)의 로이신 저급알킬에스테르를 트랜스-에폭시석신산 모노에스테르와 반응시키고 반응후에 모노에스테르 잔기를 제거하고, 염이 필요하면 생성된 유도체를 공지된 방법으로 무독성염으로 전환시키는 것을 특징으로하여 다음 일반식(Ⅰ)의 에폭시석신산 유도체 또는 그의 무독성염을 제조하는 방법.The leucine lower alkyl ester of formula (II) is then reacted with a trans-epoxysuccinic acid monoester, after the reaction to remove the monoester residues, and if salts are required, the resulting derivatives are converted to non-toxic salts by known methods. To prepare an epoxy succinic acid derivative of the following general formula (I) or a non-toxic salt thereof. 상기식에서In the above formula R은 메틸, 에틸, n-프로필, n-부틸 및 이소부틸그룹가운데 선택한 저급알킬그룹을 나타낸다.R represents a lower alkyl group selected among methyl, ethyl, n-propyl, n-butyl and isobutyl groups. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
