実験手順
3-Amino-7-methylsulfonylamino-6-phenoxy-4H-1-benzopyran-4-one was reacted with N-tert-butoxycarbonylalanine in the presence of dicyclohexylcarbodiimide. The reaction product was treated with trifluoroacetic acid to obtain 3-(2-aminopropionyl)amino-7-methylsulfonylamino-6-phenoxy-4H-1-benzopyran-4-one.
