Reaction Steps

A solution of 2-methoxyethanol (7 μL, 89 μmol) in dry tetrahydrofuran (500 μL) is cooled at 78° C. and treated with sodium hydride (60% in mineral oil, 9 mg, 0.14 mmol). After 30 min, 4-nitrophenyl 4-(4-cyanophenyl)-2,5-dioxo-1-(3-(trifluoromethyl)phenyl)-1,2,5,6,7,8-hexahydroquinazoline-3(4H)-carboxylate (intermediate 37, 50 mg, 87 μmol) is added and the mixture is stirred at room temperature for 2 h. Water is added and the mixture is purified by preparative HPLC (Waters Xbridge™-C18, gradient of acetonitrile in water, 0.1% NH3). Yield: 8 mg; ESI mass spectrum [M+H]+=514; Retention time HPLC: 0.64 min (X012_S01).
