Procedure

Anhydrous N-hydroxybenzotriazole (1.3 g) was added to a cooled solution of 3-[5-(2-formylhydrazino)-2-methoxyphenyl]propionic acid (1.2 g) and 5-aminobenzotriazole (0.67 g, 0.005 mole) in dry dimethylformamide (10 ml). A solution of dicyclohexylcarbodi-imide (1.1 g) was added dropwise to the solution of reactants at such a rate that the temperature was kept at 0°.
