Procedure
A solution of 50.0 mg (0.13 mmol) 2-hydroxy-4-methyl-2-((S)-6-oxo-6,7-dihydro-5H-dibenzo[b,d]azepin-7-ylcarbamoyl)-pentanoic acid and 39.0 mg (0.26 mmol) 2,2,3,3,3-pentafluoropropylamine in 1.5 ml dimethylformamid was cooled to 0° C. and 20 μl (0.14 mmol) triethylamine and 54.5 mg (0.14 mmol) O-(benzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (HBTU) were added. Stirring was continued overnight. Removal of the solvent by distillation and chromatography on silicagel with heptane/ethylacetate (gradient 19:1 to 1:1) yielded 45.0 mg (67%) (R/S)-2-hydroxy-2-isobutyl-N-((S)-6-oxo-6,7-dihydro-5H-dibenzo[b,d]azepin-7-yl)-N-(2,2,3,3,3-pentafluoro-propyl)-malonamide: MS (m/e): 514.5 (M+H)+.
