Procedure

138.2 mg (0.65 mmol) of 4-biphenylacetic acid and 99.7 mg (0.65 mmol) of 1-hydroxy-1H-benzotriazole hydrate are initially charged at room temperature in 5 ml of dimethylformamide. 150 mg (0.72 mmol) of 2-methylamino-4-methyl-1,3-thiazole-5-sulphonamide and 138.7 mg (0.72 mmol) of N′-(3-dimethylaminopropyl)-N-ethylcarbodiimide hydrochloride are added, and the mixture is stirred at room temperature for 72 h. The reaction mixture is then filtered off with suction and the residue is recrystallized from 2-propanol. This gives a white solid.
