| titleOfInvention | A kind of preparation method of bixalomer intermediate |
| abstract | The present invention obtains 3 nitrine, 1 propylene with allyl bromide, bromoallylene as raw material under sodium azide effect, 3 nitrine, 1 propylene obtains N, N with Isosorbide-5-Nitrae butanediamine addition, N, N tetra- (3 Azidopropyl) Isosorbide-5-Nitrae butanediamine, then carry out hydrogenation reaction and obtain N, N, N, N tetra- (3 aminopropyl) Isosorbide-5-Nitrae butanediamine.Raw material of the method used by which are cheap and easy to get, reacted using one kettle way, easy to operate, high income, product purity preferably, the purity of HPLC detection tetramino propyl group Isosorbide-5-Nitrae butanediamine is more than 99%, the three wastes that preparation technology used is produced are few, therefore have extraordinary industrial prospect. |
