Procedure

A suspension of 2,6-difluoro phenol (18 g, 0.385 mol), 1,2-dibromoethane (71.6 ml, 0.83 mol) and K2CO3 (47.86 g, 0.3463 mol) in dry acetonitrile (190 ml) was stirred at 60° C. overnight under nitrogen atmosphere. The reaction mixture was filtered and solvent concentrated under reduced pressure. The residue was purified by column chromatography over silica gel using 7% ethyl acetate in petroleum ether as eluent to give the title compound (20.8 g) as colorless oil.
