    摘要: 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.

    摘要: The present invention relates to a method for preparing difluoracetonitrile and the derivatives thereof. The method for preparing difluoroacetonitrile according to the invention is characterized in that it includes reacting halogenodifluoromethane and a source of cyanide anions in an alkaline medium. The invention also relates to the use of difluoroacetonitrile as an intermediate in the manufacture of difluoroacetic acid and the salts, esters, or amide thereof
