2-(2-溴苯基)-2-氧代乙酸甲酯

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: 5.2 g (62 mmol) of 0-methylhydroxylamine hydrochloride is added to a solution of 10 g (41 mmol) of methyl 2-bromophenylglyoxylate in 30 ml of methanol, and the mixture is refluxed for 2 hours. The mixture is evaporated down, and the residue is taken up in ethyl acetate and washed with water. After drying and evaporating down, there remains 6.9 g (62%) of compound E. the mixture is refluxed for 2 hours The mixture is evaporated down washed with water After drying evaporating down
