| titleOfInvention | 2- nitro -4- aminobenzaldehyde pharmaceutical intermediate synthetic methods |
| abstract | The invention discloses 2 nitro, 4 aminobenzaldehyde pharmaceutical intermediate synthetic methods, include the following steps：2,4 dinitrobenzene methanol are added in reaction vessel, Klorvess Liquid controls mixing speed, increases solution temperature, adds in potassium persulfate, the reaction was continued；Then cyclopropane solution is added in, adds in oxalic acid cobalt dust, increases solution temperature, the reaction was continued, it stands, then reduces temperature, add in sodium nitrate solution, solution is layered, oil-yielding stratum is detached, is washed with trimethylamine solution, is recrystallized in hexadecanol solution, dehydrating agent is dehydrated, and obtains 2 nitro of finished product, 4 aminobenzaldehyde. |
