N-allyl-2,6-diisopropyl aniline (18.33 g, 0.084 mol) and ZnCl2 (13.6 g, 0.1 mol) were added to a 100 ml toluene solution. This solution was refluxed for 5 hr and then poured into a NaOH aqueous solution. Extraction with Et2O (3×50 ml) and distillation (79.93 Pa, 98° C.) yielded 13.0 g (70.9%) of 4-allyl-2,6-diisopropyl aniline.
