Dichloromethane → Methyl 2-(benzamido)-4-bromobenzoate

Participants

Reaction Steps

0.55 mL of benzoyl chloride was added to 10 mL of a methylene chloride solution containing 1.0 g of methyl 2-amino-4-bromobenzoate and 0.73 mL of triethylamine while ice-cooled and stirred at room temperature for 1 hour. The solvent was evaporated under reduced pressure and a saturated sodium hydrogen carbonate aqueous solution and ethyl acetate were added to the residue. The organic layer was separated and dried over anhydrous magnesium sulfate after washed with 1.0 mol/L hydrochloric acid and a saturated sodium chloride aqueous solution sequentially, and the solvent was evaporated under reduced pressure. Diisopropyl ether was added to the obtained residue and a solid substance was separated by filtration to obtain 0.9 g of methyl 2-(benzamido)-4-bromobenzoate as while solid.
