実験手順: 215.3 mg (0.89 mmol) of tert-butyl 3-(3-aminophenyl)propanoate were added to a solution of 280.0 mg (0.71 mmol) of 4,4,4-trifluoro-2-{4-[(4-fluoro-1-oxo-1,3-dihydro-2H-isoindol-2-yl)methyl]phenyl}-3-methylbutanoic acid and 114.8 mg (0.85 mmol) of 1-hydroxy-1H-benzotriazole hydrate in 1.4 ml of DMF. At 0° C., 308 μl (1.77 mmol) of DIEA and then, a little at a time, 296.2 mg (0.78 mmol) of HATU were added to the resulting mixture. The reaction mixture was then slowly warmed to RT and subsequently stirred at RT for 2.5 h. The mixture was added to water and extracted three times with ethyl acetate. The combined organic phases were dried over magnesium sulfate and concentrated under reduced pressure. The crude product was purified by preparative RP-HPLC (mobile phase: acetonitrile/water gradient). This gave 333 mg (78.6% of theory) of the title compound. extracted three times with ethyl acetate The combined organic phases were dried over magnesium sulfate concentrated under reduced pressure The crude product was purified by preparative RP-HPLC (mobile phase: acetonitrile/water gradient)
