Reaction Steps

Potassium carbonate (67 mg, 0.486 mmol) and 1-bromo-2-(methylsulfonyl)ethane (68 mg, 0.365 mmol) are added to 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, 100 mg, 0.243 mmol) in N,N-dimethylformamide (3 mL). The mixture is heated at 50° C. for 3 d and then purified by reversed phase HPLC (first purification: Waters Xbridge™-C18, gradient of acetonitrile in water, 0.1% NH3; second purification: Waters Xbridge™-C18, gradient of acetonitrile in water, 0.1% TFA). Yield: 22 mg; ESI mass spectrum [M+H]+=518; Retention time HPLC: 0.86 min (Z011_S03).
