Participants

Reaction Steps

Cesium carbonate (39 mg, 0.12 mmol) and methyl idodide (6 μL, 0.10 mmol) are added to a solution of 4-(2,5-dioxo-1-(2-(trifluoromethyl)pyridin-4-yl)-1,2,3,4,5,6,7,8-octahydroquinazolin-4-yl)benzonitrile (example 14, 25 mg, 61 μmol) in N,N-dimethylformamide (1 mL). The mixture is stirred at room temperature for 1 h, diluted with aceontrile and purified by preparative HPLC (Waters SunFire™-C18, gradient of acetonitrile in water, 0.1% TFA). Yield: 13 mg; ESI mass spectrum [M+H]+=427; Retention time HPLC: 1.02 min (Z018_S04).
