Reaction Conditions

Reaction Steps

An aqueous hydrogen bromide solution (80 μL) was added to a mixed solution of 3-tert-butyl-5,7-dimethyl-6-{2-[2-(4-methyl-cyclohexyl)-4-oxo-1,3,8-triaza-spiro[4.5]dec-1-ene-8-sulfonyl]-ethyl}-1H-quinazoline-2,4-dione (3.3 mg, 3.41 μmol) in acetic acid (80 μL), and the mixture was heated with stirring at 100° C. for one hour. The reaction solution was returned to room temperature and then concentrated under reduced pressure, and the resulting residue was purified by preparative TLC to give 5,7-dimethyl-6-{2-[2-(4-methyl-cyclohexyl)-4-oxo-1,3,8-triaza-spiro[4.5]dec-1-ene-8-sulfonyl]-ethyl}-1H-quinazoline-2,4-dione as a pale yellow solid (1.2 mg, 44%).
