Reaction Steps

To a solution of 4-benzyloxy-3,5-difluorophenylamine (3.0 g) in THF (30 mL) was added N-bromosuccinimide (2.32 g) under ice-cooling, and the mixture was stirred for 30 minutes. Conc. Hydrochloric acid (2 mL) was added to the reaction mixture to precipitate a solid. The solid was collected by filtration and dried. The dried solid was dissolved in water, and the solution was added with saturated aqueous sodium bicarbonate, and then extracted with ethyl acetate. The extract was dried over sodium sulfate and concentrated to give 4-benzyloxy-2-bromo-3,5-difluorophenylamine (3.33 g).
