Mode opératoire

A mixture of 2-bromo-4′-trifluoromethylacetophenone (40.0 g), sodium formate (40.0 g) and methanol (200 mL) was heated under reflux and stirred for 6 h. The reaction mixture was concentrated and poured into water (500 mL). The precipitated solid was collected by filtration, washed with water and air-dried to give the title compound as crystals (24.5 g, 80%). melting point: 112-114° C.
