Procedure

293 mg of N-[5-[[N-(t-butoxycarbonyl)-β-alanyl]amino]anthraniloyl]-β-alanine t-butyl ester are stirred at 20° C. for 3 hours in 1.3 ml of trifluoroacetic acid. The solvent is evaporated in a vacuum, the residue is dissolved in water and evaporated in a vacuum. There are obtained 324 mg of N-[5-(β-alanylamino)anthraniloyl]-β-alanine trifluoroacetate (1:2), MS: 295 (100, M+H).
