1-[1-(2-Toluoylmethyl)-2-oxo-5-(2-thenoyl)-8-methyl-1,3,4,5-tetrahydro-2H-1,5-benzodiazepin-3-yl]-3-(3-tert-butoxycarbonylphenyl)urea (3.35 g) was dissolved in trifluoroacetic acid (30 ml), and then stirred for one hour at room temperature. The reaction mixture was concentrated under reduced pressure, hexane was added to the residue for trituration, and collected by filtration, to thereby obtain 3.04 g of the title compound as colorless powder (Yield: 99%).
