To a solution of 1-{4-[2-(benzyloxy)-4-ethylphenoxy]-3-fluorophenyl}ethanone (3 g, 8.24 mmol) in dry dichloromethane (30 ml), was added PTSA (0.047 g, 0.247 mmol). The reaction mixture was cooled in an ice bath and mCPBA (50% H2O)(2.84 g, 8.24 mmol) was added portionwise. The resulting mixture was stirred at RT for 3 days, then concentrated at 35-40 C. The residue was purified by column chromatography, (pet ether:EtOAC). The resulting solid was dissolved in pet ether, filtered then concentrated the yield the title compound (1.6 g; 51%)
