Procedure

In a sealed Pyrex tube, a mixture of 3,5-difluorophenol (2.19 g, 16.8 mmol), ethylene carbonate (1.0 g, 11.4 mmol), a catalytic amount of NaH (60% in mineral oil) in DMF (1 mL) was reacted in a Labwell MW-10 microwave reactor at 50W for 3 min. The reaction mixture was diluted with toluene and washed with 5% aqueous NaOH. The organic phase was dried (MgSO4) and concentrated. This gave 1.59 g (80%) of the title compound as a light red oil. MS m/z 174 (M)+.
