YieldReaction ConditionsOperation in experiment
56.3% With N-Bromosuccinimide; sulfuric acid; In water; at 20 - 60℃; for 1.5h; Step 2: l-(Difluoromethyl)-3-nitrobenzene (866 mg, 5.00 mmol) was added to cold cone.H2SO4 and then NBS (890 mg, 5.00 mmol) was added. The mixture was warmed to room temperature for 30 minutes then 50-60 C for 1 h. The mixture was then poured in water and ice and extracted diethyl ether twice. The organic layer was washed with dilute aqueous NaHC03 and brine. Purification by chromatography on silica gel (0-15% ethyl acetate in hexanes) yielded l-bromo-3-(difluoromethyl)-5-nitrobenzene (710 mg, 2.82 mmol, 56.3%).
