実験手順

(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) is added to a suspension of sodium hydride (60% in mineral oil, 11 mg, 0.29 mmol) and tetrahydrofuran (3 mL), and the mixture is stirred at room temperature for 10 min. Methanesulfonyl chloride (16 μL, 0.22 mol) is added, and the mixture is heated at 50° C. for 2 h. The mixture is cooled at room temperature, diluted with water (0.5 mL) and purified by preparative HPLC (Waters Xbridge™-C18, gradient of acetonitrile in water, 0.1% TFA). Yield: 37 mg; ESI mass spectrum [M+H]+=568; Retention time HPLC: 0.81 min (005_CA01).
