A solution of 70 mg (0.31 mmol) of (2S,3R)-2-(4-chlorophenyl)-4,4,4-trifluoro-3-methylbutanoic acid, 84 mg (0.31 mmol) of methyl [1-(3-amino-4-fluorophenyl)cyclopropyl]acetate, 179 mg (0.47 mmol) of 2-(1H-7-azabenzotriazol-1-yl)-1,1,3,3-tetramethyluronium hexafluorophosphate (HATU) and 0.6 ml of pyridine in 2.4 ml of DMF was stirred at room temperature overnight. After the reaction had ended, the mixture was separated directly, without further work-up, by preparative HPLC. This gave 106 mg (0.22 mmol, 72% of theory) of the title compound as a colourless oil.
