Reaction Steps
A suspension of 416 g of 4-bromo-2,6-difluoroaniline, 752 g of benzyl bromide and 608 g of potassium carbonate in 2 l of acetonitrile is refluxed for 48 hours. The mixture is subsequently evaporated in a rotary evaporator, the residue is dissolved in toluene and extracted with hydrochloric acid (10%), the toluene phase is evaporated in a rotary evaporator, and the product is stirred into heptane and stirred with silica gel for about 4.5 hours, filtered with suction and evaporated in a rotary evaporator, giving dibenzyl(4-bromo-2,6-difluorophenyl)amine, yield 85.6%.
