Versuchsvorschrift

Trimethyl phenylammonium tribromide (13 g, 0.036 mol) was added to a solution of 1-(4-bromo-3-methyl-phenyl)-ethanone (6.3 g, 0.030 mol) in THF (30 mL) and the reaction mixture was stirred at RT for 12 h, filtered, and concentrated to provide the title intermediate (8.6 g, 100% yield). 1H NMR (CDCl3, 400 MHz) δ (ppm): 7.82 (m, 1H), 7.66 (m, 2H), 4.38 (s, 2H), 2.56 (s, 3H)

Aufarbeitung

  1. filtrationfiltered
  2. concentrationconcentrated
