Versuchsvorschrift

To a 50 mL round-bottomed flask was added 4-(4-chloro-1-methyl-1H-pyrazol-5-yl)-5-(methyloxy)-2-thiophenecarboxylic acid (220 mg, 0.81 mmol) [prepared according to the procedure of Example 188], 2-[(2S)-2-amino-3-(3-fluorophenyl)propyl]-1H-isoindole-1,3(2H)-dione (281 mg, 0.84 mmol) [prepared according to the procedure of Preparation 6, except substituting N-{[(1,1-dimethylethyl)oxy]carbonyl}-3-fluoro-L-phenylalanine (5.03 g, 17.8 mmol) for N-{[(1,1-dimethylethyl)oxy]carbonyl}-2-(trifluoromethyl)-L-phenylalanine] and PyBrop (472 mg, 1.0 mmol) in Chloroform (8 mL). DIEA (710 μL, 4.07 mmol) was added and the reaction stirred overnight at room temperature. The mixture was adsorbed onto silica and purified via column chromatography (25-70% EtOAc/Hex) affording the title compound (281 mg, 0.51 mmol, 63%): LC-MS (ES) m/z=553 (M+H)+.
