Procedure

Trimethyloxonium tetrafluoroborate (320 mg, 2.16 mmol) is added to a solution of 1-((4-cyanophenyl)(8-hydroxy-10-oxo-3-oxaspiro[5.5]undec-8-en-9-yl)methyl)-3-(3-(trifluoromethyl)phenyl)urea (intermediate 10, 712 mg, 1.43 mmol) and N,N-diisopropylethylamine (490 μL, 2.81 mmol) in dichloromethane (20 mL). The mixture is stirred at room temperature for 30 min and washed with water. The organic layer is concentrated under reduced pressure, and the residue is purified by reversed phase HPLC (Waters Xbridge™-C18, gradient of acetonitrile in water, 0.1% TFA). Yield: 380 mg; ESI mass spectrum [M+H]+=514, Retention time HPLC: 1.18 min (V012_S01).
