Procedure

A solution consisting of (2-bromo-6-fluorophenoxy)(tert-butyl)dimethylsilane (0.832 g, 2.73 mmol) and bis(tri-tert-butylphosphine)palladium(0) (0.070 g, 0.14 mmol) and dry THF (5 mL) was treated with cyclohexylzinc(II) bromide (7.0 mL, 3.5 mmol, 0.5 M in THF). The resultant mixture was heated for 45 minutes at 50° C., cooled to rt, and concentrated to dryness. The resultant residue was subjected to FCC purification to the title compound (0.841 g, 89%) which was used without purification.
