5933-32-4 - Reference Information
| Application | p-bromobenzoyl hydrazine is an organic intermediate that can be prepared by reacting methyl 4-bromobenzoate with hydrazine hydrate. It has been reported in the literature to be useful in the preparation of 1,3, 4-oxadiazoles and their derivatives. |
| preparation | Add p-bromobenzoic acid (10.0g,49.75mmol) and 100mL Tetrahydrofuran, then add N,N'-carbonyl diimidazole (10.45g,64.68mmol),TLC monitor raw material reaction is complete, after the reaction is finished, slowly add 80% hydrazine hydrate (4.93g,78.77mmol), drop finish, stirred for about 6 hours. TLC was used to monitor whether the reaction of the starting material was complete (developing solvent: petroleum ether /ethyl acetate 1:1). After completion of the reaction, the reaction mixture was cooled to room temperature, and concentrated under reduced pressure to remove most of the organic solvent. About 30ml of water was added, and the mixture was pulped at room temperature for a while, suction filtered, and washed with water to obtain a white flaky solid. Recrystallization from 15mL absolute ethanol gave 9.09g of a white solid of intermediate 3, yield 85%. m. P. 166~167 ℃, consistent with the literature value. |
