Versuchsvorschrift
2-[(5-bromo-2-chloro-3-fluorophenyl)oxy]-4-(bromomethyl)-1-chloro-3-fluorobenzene (10.04 g, 22.47 mmol) and sodium azide (1.461 g, 22.47 mmol) were combined in DMSO (50 mL) and stirred 3 days at 25° C. The reaction mixture was diluted with EtOAc, washed 4× with water, dried over MgSO4, filtered and concentrated to dryness to give 1-(azidomethyl)-3-[(5-bromo-2-chloro-3-fluorophenyl)oxy]-4-chloro-2-fluorobenzene (8.3 g, 20.29 mmol, 90% yield) as a clear oil. 1H NMR (400 MHz, DMSO-d6) δ ppm 7.49-7.66 (m, 3H), 6.80 (s, 1H), 4.61 (s, 2H).
