Vorschrift

Potassium carbonate (67 mg, 0.486 mmol) is added to a solution of 4-(2,5-dioxo-1-(3-(tri-fluoromethyl)phenyl)-1,2,3,4,5,6,7,8-octahydroquinazolin-4-yl)-benzonitrile (example 1, 100 mg, 0.243 mmol) in N,N-dimethylformamide (3 mL). 3-(Bromomethyl)tetrahydrofuran (60 mg, 0.365 mmol) is added, and the mixture is stirred at room temperature for 1 h and purified by reversed phase HPLC (Waters Xbridge™-C18, gradient of acetonitrile in water, 0.1% NH3). Yield: 12 mg; ESI mass spectrum [M+H]+=496; Retention time HPLC: 0.91 min (Z011_S03).
