Procedure
Aqueous sodium hydroxide solution (1.0 M, 10.0 mL, 10.0 mmol) is added to a solution of ethyl 2-(4-(4-cyano-2-(methylsulfonyl)phenyl)-2,5-dioxo-1-(3-(trifluoromethyl)phenyl)-6,7-dihydro-1H-cyclopenta[d]pyrimidin-3(2H,4H,5H)-yl)acetate (intermediate 29, 1.80 g, 3.20 mmol) in tetrahydrofuran (40 mL), and the mixture is stirred at room temperature over night. Another portion of aqueous sodium hydroxide solution (4.0 M, 2.0 mL, 8.0 mmol) and methanol (5.0 mL) is added, and mixture is stirred over night. Aqueous hydrogen chloride (1.0 M, 10 mL) is added, and the mixture is extracted with ethyl acetate. The organic layer is concentrated under reduced pressure, and the residue is purified reversed phase HPLC (Waters SunFire™-C18, gradient of acetonitrile in water, 0.1% TFA). Yield: 229 mg; ESI mass spectrum: [M+H]+=534; Retention time HPLC: 0.96 min (Z018_S04).
