3,5-二氯-4-羟基苯甲酰肼

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

实验步骤: A mixture of 8.9 g 3,5-dichloro-4-hydroxybenzoic acid hydrazide and 500 ml triethyl orthoformate was stirred and heated at reflux for 4 hrs. The solvent was removed in vacuo to afford the product (9.9 g) as a yellow solid, used directly in the next reaction. heated at reflux for 4 hrs The solvent was removed in vacuo
