Procedure

Sodium hydride (60% in mineral oil, 15 mg, 0.38 mmol) is added to a solution of 4-(2,5-dioxo-1-(3-(trifluoromethyl)phenyl)-1,2,3,4,5,6,7,8-octahydroquinazolin-4-yl)-3-methylbenzonitrile (example 55, 60 mg, 0.13 mmol) in tetrahydrofuran (3 mL), and the mixture is stirred at room temperature for 20 min. Methanesulfonyl chloride (22 μL, 0.28 mmol) is added, and the mixture is stirred at room temperature over night. Another portion of sodium hydride (60% in mineral oil, 5 mg, 0.13 mmol) and methanesulfonyl chloride (10 μL, 0.13 mmol) is added, and the mixture is stirred for 1 h and purified by preparative HPLC (Waters Xbridge™-C18, gradient of acetonitrile in water, 0.1% TFA). Yield: 28 mg; ESI mass spectrum [M+H]+=504; Retention time HPLC: 0.71 min (X012_S01).
