Reaction Steps

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, 200 mg, 0.49 mmol) in tetrahydrofuran (4 mL) is cooled in an ice bath. Lithium diisopropylamide (2 M in tetrahydrofuran, 270 μL, 0.54 mmol) is added, and the mixture is stirred for 15 min. Ethyl 2-bromo-2-fluoroacetate (135 mg, 0.73 mmol) is added, and the mixture is warmed at room temperature and stirred over night. Water is added, and the mixture is extracted twice with dichloromethane. The combined organic layers are concentrated under reduced pressure, and the residue is purified by preparative HPLC (Waters Xbridge™-C18, gradient of acetonitrile in water, 0.1% TFA). Yield: 70 mg; ESI mass spectrum [M+H]+=516; Retention time HPLC: 0.67 min (X012_S01).
