| Zusammenfassung: | A method for producing antifolate agents having glutamic acid part in their structure is developed by protecting carboxyl groups of glutamic acid or its N-substituted derivatives as cyanomethyl ester to give compounds of formula (II) which are hydrolyzed under very mild conditions to afford antifolate agents in high yield with high analytical and optical purity. |
