Participants

Reaction Steps

t-Butyl N-(2-methoxybenzyl)carbamate (6.04 g) was dissolved in 50 ml of acetonitrile, and 4.6 g of N-bromosuccinimide was added thereto. The mixture was stirred at room temperature for 3 hours, and then the solvent was evaporated. The residue was dissolved in ethyl acetate and successively washed with water and brine. The organic layer was dried over anhydrous magnesium sulfate, and the solvent was evaporated. The residue was washed with a mixed solvent of t-butyl methyl ether and hexane, to give 6.97 g of the title compound.
