Sodium hydride (60% in mineral oil, 895 mg, 22.4 mmol) is added in portions to a mixture of 3-(2-(trifluoromethyl)pyridin-4-ylamino)cyclopent-2-enone (intermediate 17, 4.52 g, 18.7 mmol) and 2-methyltetrahydrofuran (30 mL). After 30 min tert-butyl (4-cyano-phenyl)(phenylsulfonyl)methylcarbamate (6.90 g, 18.5 mmol) is added, and mixture is stirred at room temperature for 30 min Water is added, and the phases are separated. The organic phase is dried over Na2SO4 and concentrated under reduced pressure. Yield: 9.20 g; ESI mass spectrum [M+H]+=473; Retention time HPLC: 1.09 min (Z018_504).
