| titleOfInvention | A kind of refining methd for the imidazole diketone analog derivative that trifluoromethyl replaces |
| abstract | The present invention provides a kind of refining methds for the imidazole diketone analog derivative that trifluoromethyl replaces, this method is handled by soda acid and is recrystallized again, recrystallization solvent for use is DMF- acetonitrile mixed solvent system, pass through the refining methd, the HPLC purity for the imidazole diketone analog derivative crude product that trifluoromethyl to be refined can be made to replace is promoted from 98% to 99.5% or more, and the refining methd is easy to operate, the period is short, single miscellaneous content is controllable. |
