A solution of 3-(3-(trifluoromethyl)phenylamino)cyclopent-2-enone (900 mg, 3.73 mmol) in dichloromethane (8 mL) is added dropweise to a solution of 2-chloro-5-(chloro(iso-cyanato)methyl)pyridine (intermediate 10, 757 mg, 3.73 mmol) in dichloromethane (7 mL). The mixture is stirred at room temperature for 2 h and concentrated, and the residue is purified by reversed phase HPLC (Waters Xbridge™-C18, gradient of acetonitrile in water, 0.1% NH3). Yield: 160 mg; ESI mass spectrum [M+H]+=408; Retention time HPLC: 0.98 min (V011_S01).
