Participants

Reaction Steps

In analogy to Example 70.4–6, from the methyl (RS)-(3-amino-4-methoxy-phenyl)-(4-cyano-phenylamino)-acetate described in Example 70.3, glutaric anhydride and Hünig's base in DMF there was obtained (RS)-4-{5-[(4-cyano-phenylamino)-methoxycarbonyl-methyl]-2-methoxy-phenylcarbamoyl}-butyric acid, which was subsequently converted via (RS)-4-{5-[carboxy-(4-cyano-phenylamino)-methyl]-2-methoxy-phenylcarbamoyl}-butyric acid into (RS)-(E)- and/or -(Z)-4-(5-{carboxy-[4-(N-hydroxycarbamimidoyl)-phenylamino]-methyl}-2-methoxy-phenylcarbamoyl)-butyric acid.
