1-(溴甲基)-4-氯-2-碘苯

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: 1-(4-Chloro-2-iodo-benzyl)-1H-indazole-5-carbaldehyde was prepared from 1H-indazole-5-carbaldehyde and 1-Bromomethyl-4-chloro-2-iodo-benzene following General Procedure A.

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: A mixture of 4-chloro-2-iodo-1-methylbenzene (3.95 g, 15.6 mmol), N-bromosuccinimide (3.10 g, 17.6 mmol), and benzoyl peroxide (0.1 g) in carbon tetrachloride (100 mL) was heated to reflux for 48 hours, filtered, and concentrated. The concentrate was purified by flash column chromatography on silica gel with 4:100 ethyl acetate/hexanes to provide 3.34 g (64%) of the desired product. MS (DCI/NH3) m/z 330, 332 (M+H)+; 1H NMR (CDCl3) δ 7.85 (d, 1H), 7.40-7.32 (m, 2H), 4.59 (s, 2H). was heated to reflux for 48 hours filtered concentrated The concentrate was purified by flash column chromatography on silica gel with 4:100 ethyl acetate/hexanes
