The mixture of 500mg of 3-chlorobenzotrifuluoride and 3ml of tetrahydrofuran was cooled down to -50C and 2ml of 1.6M n-butyllithium hexan solution was added and stirred for 1 hour. The mixture was put into dry ice and diluted by an aqueous solution of 1N sodium hydroxide. After washing it with toluene, the water layer was made acidic by hydrochloric acid and extracted with ethyl acetate. The crude material obtained by removing the solvent was purified by reverse phase HPLC to the said compound. Yield 244mg H-NMR (DMSO-d6) δ 7.68 (1H, t), 7.80 (1H, d), 7.88 (1H, d).
