Procedure

Sodium tert-butoxide (175 mg, 1.82 mmol) is added to a solution of 1-((4-bromo-2-methoxyphenyl)(2-ethoxy-6-oxocyclohex-1-enyl)methyl)-3-(3-(trifluoromethyl)phenyl)-urea (intermediate 49, 760 mg, 1.40 mmol) in acetonitrile (4 mL), and the mixture is shaked in an ultrasound bath for 20 min Water is added, and the mixture is extracted with dichloromethane. The combined organic layers are dried over Na2SO4 and concentrated under reduced pressure. The residue is purified by reversed phase HPLC (Waters Xbridge™-C18, gradient of acetonitrile in water, 0.1% NH3). Yield: 41 mg; ESI mass spectrum [(79Br)-M+H]+=495, [(81Br)-M+H]+=497; Retention time HPLC: 0.96 min (Z011_S03).
