Versuchsvorschrift

500 mg (2.07 mmol) of ethyl (−)-(2R)-3-(3-amino-4-chlorophenyl)-2-methylpropanoate and 607 mg (2.28 mmol) of (2S,3R)-2-(4-chlorophenyl)-4,4,4-trifluoro-3-methylbutanoic acid were dissolved in a mixture of 2.0 ml of DMF and 1.0 ml of pyridine, and 1022 mg (2.69 mmol) of HATU were added at room temperature. The reaction mixture was stirred at RT overnight. The mixture was diluted with ethyl acetate, and the solution was washed successively with 1 N hydrochloric acid, water, saturated sodium bicarbonate solution and saturated sodium chloride solution. The organic phase was dried over magnesium sulphate and concentrated under reduced pressure. The residue was purified by chromatography on silica gel (mobile phase cyclohexane/ethyl acetate 40:1). This gave 998 mg (98.4% of theory) of the target compound.
