Participants

Reaction Steps

Methylamine (2.0 M in tetrahydrofuran, 69 μL, 138 μmol) is added to a solution of 4-nitrophenyl 4-(4-cyano-2-(methylsulfonyl)phenyl)-2,5-dioxo-1-(3-(trifluoromethyl)phenyl)-1,2,5,6,7,8-hexahydroquinazoline-3(4H)-carboxylate (intermediate 38, 30 mg, 46 μmol) in acetonitrile (1 mL). The mixture is stirred at room temperature for 20 min and purified by reversed phase HPLC (Agilent ZORBAX™ SB-C18, gradient of acetonitrile in water, 0.15% formic acid). Yield: 22 mg; ESI mass spectrum M+H]+=547, Retention time HPLC: 1.01 min (Z017_S04).
