Claims (2)
- L-페닐알라닌을 강산 촉매의 존재하에서 메탄올로 에스테르화시키고, 생성된 용액에 알카리 수용액을 가하여 산촉매를 중화시키고 수비혼화성 유기용매를 가하여 생성된 유리 L-페닐알라닌 메틸 에스테르를 추출하고, 유기층을 회수한 후, 회수된 유기층중에 용해되어 있는 L-페닐알라닌 메틸 에스테르를 N-보호된-L-아스파르트산 무수물과 반응시킴을 특징으로 하여, N-보호된-α-L-아스파르틸-L-페닐알라닌 메틸 에스테르를 제조하는 방법.
- 제 1 항에 있어서, 메탄올의 일부 또는 전부를 N-보호된-L-아스파르트산 무수물과의 반응전에 상기 회수된 유기층으로부터 제거시킴으로써, N-보호된-α-L-아스파르틸-L-페닐알라닌 메틸 에스테르를 제조하는 방법.
