Reaction Steps

N,N,N′,N′-Tetramethyl-O-(benzotriazol-1-yl)uronium tetrafluoroborate (50 mg, 0.16 mmol) and N,N-diisopropylethylamine (60 μL, 0.34 mmol) are added to a solution of 4-(4-cyanophenyl)-2,5-dioxo-1-(3-(trifluoromethyl)phenyl)-1,2,3,4,5,6,7,8-octahydroquina zoline-7-carboxylic acid (example 10, 70 mg, 0.154 mmol) in N,N-dimethylformamide (1.0 mL). After 10 min aqueous ammonia (35%, 0.5 mL) is added and the mixture is stirred at room temperature for 1 h. Water is added and the mixture is extracted with diethyl ether. The organic layer is concentrated under reduced pressure, and the residue is purified by reversed phase HPLC (Waters Xbridge™-C18, gradient of methanol in water, 0.1% TFA). Yield: 15 mg; ESI mass spectrum [M+H]+=455; Retention time HPLC: 1.02 min (V001—006).
