Reaction Steps

500 mg of 3-bromo-2-chlorobenzoic acid are placed in 12.5 ml of tetrahydrofuran in a round-bottomed flask. The reaction mixture is cooled to 0° C. with an ice bath and then 228 mg of N,O-dimethylhydroxylamine hydrochloride, 814 mg of 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride and 0.21 ml of pyridine are added thereto. The reaction mixture is subsequently stirred at ambient temperature for 16 h and the solvent is evaporated under reduced pressure. The residue is taken up between water and dichloromethane. The separated organic phase is subsequently washed once with a saturated ammonium chloride solution and once with a saturated sodium hydrogencarbonate solution, then dried over magnesium sulphate and concentrated under reduced pressure. 500 mg of compound are obtained.
