110.8 mg (0.41 mmol) of tert-butyl 1-(3-aminobenzyl)cyclopropanecarboxylate were added to a solution of 129.0 mg (0.33 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 52.9 mg (0.39 mmol) of 1-hydroxy-1H-benzotriazole hydrate in 1 ml of DMF. At 0° C., 142 μl (0.82 mmol) of DIEA and then, a little at a time, 136.5 mg (0.36 mmol) of HATU were added to the resulting mixture. The reaction mixture was then slowly warmed to RT and 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 97.4 mg (47.6% of theory) of the title compound.
