실험 절차

To a 50 mL round-bottomed flask was added 4-(4-chloro-1-methyl-1H-pyrazol-5-yl)-5-methyl-2-furancarboxylic acid (248 mg, 0.97 mmol) [prepared according to the procedure of Example 184], 2-[(2S)-2-amino-3-(4-fluorophenyl)propyl]-1H-isoindole-1,3(2H)-dione (321 mg, 0.96 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 (557 mg, 1.19 mmol) in chloroform (9.5 mL). DIEA (840 μL, 4.81 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 (167 mg, 0.26 mmol, 67%): LC-MS (ES) m/z=521 (M+H)+.
