YieldReaction ConditionsOperation in experiment
99.2% With sulfuric acid;Reflux; Taking 250 ml of three-necked bottle, adding 100 ml anhydrous ethanol, 0.5 ml of concentrated sulfuric acid and 2 - nitro -3 - bromophenylacetic acid (12.9g, 50mmol), the assembly of the thermometer and a condenser, is put into the oil bath to reflux overnight. Stopping the reaction, to container and gradually cooling to room temperature, then put into the -5 C refrigerator overnight, separate out a large amount of white floc, machines for filtering, to obtain the 12.5g white solid 2 - nitro -3 - bromo ethyl acetate, yield 99.2%.

YieldReaction ConditionsOperation in experiment
99.2% With sulfuric acid; In ethanol;Reflux; To a solutuion of 60 ml 6 N HCl and 60 ml AcOH, dissove 17.9 g 2 (50 mmol) and stir at 110 oC overnight. Romve all sovent and obtain 12.5 g 5-Bromo-2-Nitrophenylacetic acid (3), mp. 174.4-175.9 oC, yield 98%. Intermediate 3 proceed to next step without further purification. To a solution of 100 ml dehydrated EtOH and 0.5 ml conc. H2SO4, add 12.9 g 3 (50 mmol).Ethyl 2-(5-Bromo-2-Nitrophenyl)Acetate (4). Put the mixture in oil bath and reflux overnight. Cool down to rt and place at -5 oC overnight until the total precipitation occured. Filtrate white precipitate and obtain 12.5 Ethyl 2-(5-Bromo-2-Nitrophenyl)Acetate (4), yield 99.2%. White solid, mp. 50.5-52.8 oC, HPLC: 98.5%. 1H NMR (300 MHz, DMSO-d6) delta: 8.06 (dd, J = 8.7, 3.3 Hz, 1H, Ar-H), 7.93 - 7.72 (m, 2H, Ar-H), 4.08 (d, J = 2.9 Hz, 4H), 1.22 - 1.08 (m, 3H).13C NMR (75 MHz, DMSO-d6) delta: 169.42, 136.17, 132.22, 131.70, 127.42, 126.80, 60.60, 38.29, 13.97.
