A mixture of 1-fluoro-4-nitrobenzene (4.24 g, CAS Reg. No. 350-46-9), 1,1,1-trifluoro-propan-2-ol (4.56 g, CAS Reg. No. 374-01-6) and cesium carbonate (13.04 g) in CH3CN (50 mL) was heated to reflux for 10 hours. Then, the reaction mixture was cooled, acidified with conc. HCl and then distributed between ethyl acetate and water. The organic layer was separated, washed with brine and evaporated to provide the title compound (6.74 g) that was used without further purification. Rf: 0.38 (silica gel, ether/heptane 1:4).
