Participants

Reaction Steps

A solution of 1-bromo-4-(chloro(isocyanato)methyl)benzene (4.25 g, 17.24 mmol) in dichloromethane (30 mL) is added to a solution of 3-(3-(trifluoromethyl)phenylamino)-cyclohex-2-enone (4.00 g, 15.67 mmol) in dichloromethane (60 mL) and the resulting mixture is heated at reflux for 3 h and stirred at room temperature over night. All volatiles are evaporated and the residue is purified by flash chromatography on silica (gradient dichloromethane/methanol 100:0 to 98:2). Yield: 5.10 g; ESI mass spectrum: [(79Br)-M+H]+=465, [(81Br)-M+H]+=467; Retention time HPLC: 1.44 min (V001—006).
