该中间体在本合成路线中的序号:(III)Carboxilic acid (I) is converted to the correspondig acid chloride (II) and and amidated with dimethyl homoglutamate (III) to give the amide (IV). The benzyloxycarbonyl grouo of the amide (IV) is removed with H2 over Pd/C to give the amide (V), which is effectively alkylated with 6-(bromomethyl)-2,4-diaminopteridine (VI) to produce compound (VII). Finally, compound (VII) is hydrolyzed with 1N NaoH to yield MX-68.
