실험 절차

A mixture of 430 mg (1.09 mmol) (R/S)-2-hydroxy-4-methyl-2-((S)-6-oxo-6,7-dihydro-5H-dibenzo[b,d]azepin-7-ylcarbamoyl)-pentanoic acid methyl ester in 6 ml tetrahydrofuran and of 50.1 mg (1.19 mmol) lithiumhydroxide monohydrate in 3 ml water was stirred overnight at room temperature. The solvent was evaporated and the residue extracted at pH 1 with ethylacetate to yield 390 mg (94%) (R/S)-2-hydroxy-4-methyl-2-((S)-6-oxo-6,7-dihydro-5H-dibenzo[b,d]azepin-7-ylcarbamoyl)-pentanoic acid, MS (m/e): 381.0 (M−H)−.
