YieldReaction ConditionsOperation in experiment
28% With N-Bromosuccinimide; 2,2'-azobis(isobutyronitrile); In 1,2-dichloro-ethane; at 80℃; for 9h;Inert atmosphere; 3,5-Bis(bromomethyl)benzonitrile To a solution of <strong>[22445-42-7]3,5-dimethylbenzonitrile</strong> (1.00 g, 7.62 mmol, 1 euiv.) in 1 ,2-dichloroethane (76 ml_), were added A/-bromosuccinimide (2.98 g, 16.8 mmol, 2.2 equiv.) and azobisisobutyronitrile (0.250 g, 1.52 mmol, 0.2 equiv.). The reaction mixture was stirred under an argon atmosphere for 9 h at 80 C. H20 was added to the medium which was extracted three times with CH2CI2. The combined organic layers were washed with brine, dried over Na2S04 and concentrated under reduced pressure. The residue was purified by flash chromatography (25 g BioTage HP Sil cartridge, 2% to 15% EtOAc/Hexane gradient, 20 CV) to yield 3,5-bis(bromomethyl)benzonitrile (0.618 g, 28%) as white crystals. Similar data as described in literature. NMR (CDCI3, 500 MHz) delta 7.64 (s, 1 H), 7.61 (d, 2H, J= 1.2 Hz), 4.45 (s, 4H); HPLC purity: 99%, tR = 2.9 min (Method 1 ). Similar data as described in literature (Easson, M. W.; Fronczek, F. R.; Jensen, T.; Vicente, M. G. H. Bioorg. Med. Chem. 2008, 16, 3191 -3208).
