Procedimiento

A 2M n-BuLi solution (5.8 mL, 11.6 mmol) was added to a −78° C. THF solution (60 mL) of 1,3-dichloro-5-(trifluoromethyl)benzene (2.5 g, 11.6 mmol). After 45 min neat DMF (0.39 mL, 5.0 mmol) was added, and the resulting solution was allowed to warm to 0° C. gradually, quenched with NH4Cl solution, and extracted with diethyl ether. The combined extracts were dried (Na2SO4), concentrated, and purified via column chromatography to yield the title compound.
