N-bromobutanimide → Tert-butyl (5-bromo-2-methoxybenzyl)carbamate

Participants

Reaction Steps

6.04 g of t-butyl N-(2-methoxybenzyl)carbamate was dissolved in 50 ml of acetonitrile, and 4.6 g of N-bromosuccinimide was added. After stirring for 3 hours at room temperature, the solvent was evaporated. The residue was dissolved in ethyl acetate, and successively washed with water and saturated brine. The organic layer was dried over anhydrous magnesium sulfate, and the solvent was evaporated. The residue was washed with mixture solution of methyl t-butylmethyl ether and hexane, to give 6.97 g of t-butyl N-(5-bromo-2-methoxybenzyl)carbamate.
