| titleOfInvention | The synthetic method of tri- -5 β of oxygen of Cholic acids drug 3,7,12--cholanic acid |
| abstract | The invention discloses the synthetic methods of 3,7,12 three oxygen of Cholic acids drug, 5 β cholanic acids, include the following steps：3,7,12 trimethoxy steroids are added in reaction vessel for isovaleric acid, potassium sulfate solution controls solution temperature to exist, and adds in cerous nitrate powder in batches, the reaction was continued；Then isopropyl myristate solution is added in, controls mixing speed, the reaction was continued, white solid is precipitated, it is washed repeatedly with Klorvess Liquid, the washing of hexyl ether solution is multiple, and cyclohexanone solution washing is multiple, 1, it is recrystallized in 2 propylene oxide solutions, dehydrating agent dehydration obtains finished product 3,7,12 three oxygen, 5 β cholanic acids. |
