Procedure
A solution of 4-(2,5-dioxo-1-(3-(trifluoromethyl)phenyl)-1,2,3,4,5,6,7,8-octahydroquinazolin-4-yl)-benzonitrile (example 1, 60 mg, 0.146 mmol) in tetrahydrofuran (0.8 mL) is added to a suspension of sodium hydride (60% in mineral oil, 7 mg, 0.17 mmol) in tetrahydrofuran (0.5 mL). After 20 min methyl chloroformate (11 μL, 0.15 mmol) is added and the mixture is stirred at room temperature over night. Another portion of sodium hydride (60% in mineral oil, 3 mg, 0.07 mmol) is added. After 2 h, the mixture is diluted with water and N,N-dimethylformamide and then purified by preparative HPLC (Waters Xbridge™-C18, gradient of acetonitrile in water, 0.1% NH3). Yield: 8 mg; ESI mass spectrum [M+H]+=470, Retention time HPLC: 1.14 min (V011_S01).
