Procedure
A mixture of 600 mg (2 mmol) (R/S)-2-hydroxy-2-((S)-6-oxo-6,7-dihydro-5H-dibenzo[b,d]azepin-7-ylcarbamoyl)-pentanoic acid ethyl ester in 8 ml tetrahydrofuran and of 70.0 mg (2 mmol) lithiumhydroxide in 4 ml water was stirred overnight at room temperature. The solvent was evaporated and the residue extracted at pH 1 with ethylacetate to yield 450 mg (81%) (R/S)-2-hydroxy-2-((S)-6-oxo-6,7-dihydro-5H-dibenzo[b,d]azepin-7-ylcarbamoyl)-pentanoic acid, MS (m/e): 367.1 (M−H)−.
