실험 절차

To a 50 mL round-bottomed flask was added 4-(4-chloro-1-methyl-1H-pyrazol-5-yl)-5-methyl-2-thiophenecarboxylic acid (276 mg, 1.08 mmol) [Prepared according to the procedure of Example 158], 2-[(2S)-2-amino-3-(4-fluorophenyl)propyl]-1H-isoindole-1,3(2H)-dione (317 mg, 0.95 mmol) [prepared according to the procedure of Preparation 6 except substituting N-{[(1,1-dimethylethyl)oxy]carbonyl}-4-fluoro-L-phenylalanine (4.95 g, 17.5 mmol) for N-{[(1,1-dimethylethyl)oxy]carbonyl}-2-(trifluoromethyl)-L-phenylalanine] and PyBrop (612 mg, 1.31 mmol) in Chloroform (14 mL). DIEA (940 μL, 5.38 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 (319 mg, 0.50 mmol, 71%): LC-MS (ES) m/z=537 (M+H)+.
