N-bromobutanimide → Methyl 2-(bromomethyl)-3-nitrobenzoate

Participants

Reaction Steps

A suspension containing 98 g (0.5 mol) of methyl 2-methyl-3-nitrobenzoate, 100 g (0.56 mol) of N-bromosuccinimide and 1 g of benzoyl peroxide in carbon tetrachloride (800 ml), was refluxed for 3 days under irradiation with 500 W. The suspension was cooled to room temperature and subjected to filtration, whereupon the filtrate was concentrated. To the residue, ethyl ether (200 ml) and IPE (200 ml) were added, whereupon the formed crystals were collected by filtration to obtain 121 g (yield: 88.3%) of the desired product. Melting point: 65°-67° C.
