Versuchsvorschrift

To a solution of 2-{4-[2-amino-3-(4-fluorophenyl)propionyl]-3-cyclopropylmethyl-2-oxo-piperazin-1-yl}-3-naphthalen-2-yl-propionic acid methylester, 25, (37 mg, 0.068 mmol) in DMF (1 mL) are added 2-tert-butoxycarbonylamino-2-methyl-propionic acid (202 mg, 0.079 mmol), 1-hydroxybenzotriazole (20 mg, 0.148 mmol), N-methylmorpholine (41 mg, 0.41 mmol) and 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide (16 mg, 0.083 mmol) consecutively. The reaction mixture is stirred for 3 hours, quenched with aqueous NH4Cl and extracted several times with ethyl acetate. The combined extracts are dried over Na2SO4, filtered and concentrated in vacuo to a residue which is purified over silica gel (CH2Cl2/CH3OH, 13:1) to afford the desired product.
