A solution of 1-[3-(4-fluorophenoxy)phenyl]-1,4-pentanedione (19.03 g; 0.0665M) in 0.44M aqueous NaOH solution (300 ml) was refluxed for 24 hrs. After cooling, the residual solids were collected by filtration and dried to give 18 g (yield quant.) of the subtitle compound [D] as brown solids, which was used without further purification.
