| titleOfInvention | The preparation method that a kind of Ka Gelie is clean |
| abstract | The invention discloses the preparation method that a kind of Ka Gelie is clean.The method is: (1) take DMF as solvent, adopts Benzoyl chloride to carry out protective reaction to the hydroxyl of main raw material SM1 and obtains intermediate compound I; (2) take acetonitrile as solvent, intermediate compound I removes methoxyl group and obtains intermediate II under trimethyl phosphite effect; (3) with tetrahydrofuran (THF) and dehydrated alcohol or methyl alcohol for solvent, intermediate II removes benzoyl protection under sodium methylate effect, and to obtain Ka Gelie clean, purity >=99.9% of product, yield >=81.6%.The reaction conditions of the method is gentle, economic environmental protection, and yield is high, good product quality, is easy to industrial production. |
