Procedure

Trimethyloxonium tetrafluoroborate (121 mg, 0.82 mmol) is added to a solution of N,N-diisopropylethylamine (276 μL, 1.58 mmol) and 1-((6-cyanopyridin-3-yl)(2-hydroxy-6-oxocyclohex-1-enyl)methyl)-3-(3-(trifluoromethyl)phenyl)urea (intermediate 30, 346 mg, 0.804 mmol) in dichloromethane (10 mL). The mixture is stirred at room temperature over night, and another portion of trimethyloxonium tetrafluoroborate (121 mg, 0.82 mmol) is added. After 1 h the mixture is diluted with dichloromethane, and washed with water and saturated aqueous sodium chloride solution. The organic layer is dried over Na2SO4 and concentrated under reduced pressure. Yield: 300 mg; ESI mass spectrum [M+H]+=445, Retention time HPLC: 1.09 min (V011_S01).
