Procedure

Cesium carbonate (713 mg, 2.19 mmol) is added to a solution of 4-(2,5-dioxo-1-(3-(trifluoromethyl)phenyl)1,2,3,4,5,6,7,8octahydroquinazolin-4-yl)-benzonitrile (example 1, 300 mg, 0.73 mmol) and methyl 2-bromopropanoate (244 mg, 1.46 mmol) in N,N-dimethylformamide (10 mL), and the mixture is stirred at 50° C. for 6 h and at room temperature over night. Water is added, and the mixture is extracted with dichloromethane. The organic layer is extracted with water and brine, dried over MgSO4 and concentrated under reduced pressure. Yield: 353 mg; ESI mass spectrum [M+H]+=498; Retention time HPLC: 0.97 min (Z018_S04).
