Versuchsvorschrift

1-[1-(2-Toluoylmethy)-2-oxo-5-(2-pyridylcarbonyl)-8-methyl-1,3,4,5-tetrahydro-2H-1,5-benzodiazepin-3-yl]-3-(3-ethoxycarbonylphenyl)urea (466 mg) was dissolved in methanol (22 ml), aqueous lithium hydroxide monohydrate (158 mg) solution (11 mg) and tetrahydrofuran (11 ml) were added, and the mixture was refluxed for one hour. The reaction mixture was concentrated under reduced pressure, the residue was dissolved in water, the solution was washed with diethyl ether, acidified with 1N hydrochloric acid, and extracted with methylene chloride. The organic layer was washed with saturated brine, dried over anhydrous magnesium sulfate, and the solvent was evaporated under reduced pressure. Isopropyl ether was added to the residue for trituration, collected by filtration, to thereby obtain 203 mg of the titled compound.
