Sodium hydride (60% in mineral oil, 153 mg, 3.84 mmol) is added in portions to a mixture of tert-butyl (4-cyano-2-(methylsulfonyl)phenyl)(phenylsulfonyl)methylcarbamate (step 1, 1.60 g, 3.20 mmol based on 90% purity) and 2-methyltetrahydrofuran (15 mL), and the mixture is stirred at room temperature for 20 min. 3-(2-(Trifluoromethyl)pyridin-4-yl-amino)cyclohex-2-enone (intermediate 55, 940 mg, 3.70 mmol) is added, and the mixture is stirred for 2 h. Water is added, and the phases are separated. The organic layer is washed with water and concentrated under reduced pressure. The residue is purified by flash chromatography on silica (gradient dichloromethane/methanol 99:1 to 97/3). Yield: 2.10 g; ESI mass spectrum [M+H]+=565; Retention time HPLC: 0.67 min (X012_S02).
