## Abstract A new diacid monomer **9** was synthesized in five steps. Starting from the reaction of L‐leucine with phthalic anhydride in acetic acid provided (2__S__)‐4‐methyl‐2‐phthalimidylpentanoic acid (**3**) in good yield. The compound **3** was converted to (2__S__)‐4‐methyl‐2‐phthalimidylpen
