Reaction Steps

Sodium hydride (60% in mineral oil, 11 mg, 0.28 mmol) is added to a solution of (S)-4-(2,5-dioxo-1-(3-(trifluoromethyl)phenyl)-1,2,3,4,5,6,7,8-octahydroquinazolin-4-yl)-3-(methylsulfonyl)benzonitrile (example 18A, 50 mg, 0.10 mmol) in tetrahydrofuran (3 mL), and the mixture is stirred at room temperature for 20 min 2-Iodoacetonitrile (7 μL, 0.10 mmol) is added, and the mixture is stirred over night. Another portion of 2-iodoaceto-nitrile (7 μL, 0.10 mmol) is added, and the mixture is stirred over night. Another portion of 2-iodoacetonitrile (14 μL, 0.20 mmol) is added, and the mixture is stirred for 2 h, diluted with water and purified by preparative HPLC (Waters SunFire™-C18, gradient of acetonitrile in water, 0.1% TFA). Yield: 6 mg; ESI mass spectrum [M+H]+=529; Retention time HPLC: 1.05 min (Z018_S04).
