Versuchsvorschrift

Aqueous sodium hydroxide solution (1.0 M, 100 μL, 100 μmol) is added to a solution of methyl 5-((4-(4-cyanophenyl)-2,5-dioxo-1-(3-(trifluoromethyl)phenyl)-1,2,5,6,7,8-hexahydroquinazolin-3(4H)-yl)methyl)furan-2-carboxylate (example 28, 25 mg, 45 μmol) in tetrahydrofuran (2 mL), and the mixture is at room temperature over night. Another portion of aqueous sodium hydroxide solution (4 M, 100 μL, 400 μmol) is added and stiffing was continued over night. The mixture was acidified with aqueous hydrogen chloride solution to (1 M, 100 μL, 100 μmol) and purified by reversed phase HPLC (Waters Xbridge™-C18, gradient of acetonitrile in water, 0.1% TFA). Yield: 11 mg; ESI mass spectrum [M+H]+=536; Retention time HPLC: 0.91 min (Z018_S04).
