Reaction Steps
N-(tert-Butoxycarbonyl)-3-chloro-N,4-dimethylaniline (62.6 g) was dissolved in carbon tetrachloride (310 ml), and N-bromosuccinimide (52.3 g) and 2,2′-azobis(4-methoxy-2,4-dimethylvaleronitrile) (3.77 g) were added. The mixture was stirred at 55° C. for 2 hr and 75° C. for 1 hr, and hexane (500 ml) was added. The mixture was stirred under ice-cooling for 1 hr. The reaction mixture was filtrated, and the filtrate was concentrated under reduced pressure. The residue was diluted with ethyl acetate (310 ml) and washed successively with saturated aqueous sodium hydrogen carbonate solution (500 ml) and saturated brine (500 ml). The organic layer was dried over anhydrous magnesium sulfate and concentrated under reduced pressure to give 4-bromomethyl-N-(tert-butoxycarbonyl)-N-methyl-3-chloroaniline as a brown oil (75.6 g).
