Lithium diisopropylamide (1.8 M in tetrahydrofuran, 62 μL, 0.11 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 N,N-dimethylformamide (1 mL). Methyl iodide (8 μL, 0.13 mmol) is added and the mixture is stirred for 1 h. Water is added and the mixture is purified by reversed phase HPLC (Agilent ZORBAX™ SB-C18, gradient of acetonitrile in water, 0.15% formic acid). Yield: 20 mg; ESI mass spectrum [M+H]+=504; Retention time HPLC: 1.04 min (Z017_S04).
