실험 절차

1-[1-(2-Toluoylmethyl)-2-oxo-8-methyl-1,3,4,5-tetrahydro-2H-1,5-benzodiazepin-3-yl]-3-(3-ethoxycarbonylphenyl)urea (500 mg) obtained from Step 1of Example 93 was suspended in 1,2-dichloroethane (10 ml), 2-methyl-n-pentanoyl chloride (144 mg) and pyridine (87 μl) were added, the mixture was refluxed for 3 hours. Water (100 ml) and ethyl acetate (100 ml) were added to the reaction mixture, separated, the organic layer was washed with 1N hydrochloric acid, and dried over anhydrous sodium sulfate. The solvent was evaporated under reduced pressure, the residue was purified by silica gel column chromatography(n-hexane:ethyl acetate=2:1), to thereby obtain 569 mg of the titled compound (Yield: 95.7%).
