Procedure

A mixture of EXAMPLE 261B (353 mg), 1,1-difluoro-2-iodoethane (268 mg), sodium carbonate (283 mg) in N,N-dimethylformamide (10 mL) was heated at 80° C. overnight. The reaction mixture was cooled to room temperature and diluted with ethyl acetate. The organic phase was washed with water, brine, dried over magnesium sulfate, filtered, and concentrated. The residue was loaded onto silica gel column and eluted using a gradient of 0.5 to 3% methanol in dichloromethane to provide the title compound.
