1.97 g (7.14 mmol) 2-(4-Iodo-phenyl)-propionic acid (111.1) and 1.25 mL (7.14 mmol) DIPEA are added to 582 mg (7.14 mmol) ethylamine hydrochloride in 70 mL DCM. 1.64 g (8.57 mmol) N-(3-Dimethylaminopropyl)-N-ethylcarbodiimide hydrochloride and 194 mg (1.43 mmol) 1-hydroxy-7-azabenotriazole are added at 0° C. Subsequently, cooling is removed and the mixture is stirred for 20 h at rt. After that time, the mixture is washed with water and brine, dried over sodium sulphate and the solvent is evaporated.
