実験手順

Solid benzoyl peroxide (1.5 g, 6.3 mmol) was added to a benzene solution (200 mL) of 2-bromo-1-methyl-4-(trifluoromethyl)benzene (10.0 g, 41.8 mmol) and NBS (8.2 g, 46.0 mmol) and the resulting mixture was refluxed. After 16 h the resulting mixture was cooled, diluted with EtOAc, washed with water and brine, dried (Na2SO4), and dry packed onto silica gel. Column chromatography yielded the title compound.
