Procedure

A solution of 70.0 mg (0.31 mmol) (S)-7-amino-5H,7H-dibenzo[b,d]azepin-6-one and 73.9 mg (0.34 mmol) (S)-2-hydroxy-2-methyl-N-(2,2,2-trifluoro-ethyl)-malonamic acid in 6 ml tetrahydrofuran were cooled to 0° C. and 46.4 mg (0.34 mmol) 1-hydroxy-benzotriazole hydrate, 117 μl (0.69 mmol) diisopropylethylamine and 65.8 mg (0.34 mmol) N-(3-dimethylaminopropyl)-N′-ethyl-carbodiimide hydrochloride were added. Stirring was continued for 16 hours. Removal of the solvent by distillation and chromatography on silicagel with heptane/ethylacetate (gradient 100/0 to 25/75) yielded 104 mg (79%) (S)-2-hydroxy-2-methyl-N-((S)-6-oxo-6,7-dihydro-5H-dibenzo[b,d]azepin-7-yl)-N′-(2,2,2-trifluoro-ethyl)-malonamide, MS (m/e): 422.0 (M+H)+.
