The present invention provides a method for preparing (3R,5R)-7-(2-(4-flurophenyl)-5-isopropyl-3-phenyl-4-((4-hydroxymethylphenylamino)carbonyl)-pyrrole-1-yl)-3,5-dihydroxy heptanoic acid hemicalcium salt. The preparation method of the present invention is performed in a convergent synthesis manner in which main structural moieties of a (3R,5R)-7-(2-(4-flurophenyl)-5-isopropyl-3-phenyl-4-((4-hydroxymethylphenylamino)carbonyl)-pyrrole-1-yl)-3,5-dihydroxy heptanoic acid hemicalcium salt are independently synthesized, and then coupled. Accordingly, related substances can be easily controlled and preparing time can be reduced, thus improving the productivity of a compound, and the yield of a final compound can also be increased.

The emerging pharmacological target soluble epoxide hydrolase (sEH) is a bifunctional enzyme exhibiting two different catalytic activities that are located in two distinct domains. Although the physiological role of the C-terminal hydrolase domain is well-investigated, little is known about its phosphatase activity, located in the N-terminal phosphatase domain of sEH (sEH-P). Herein we report the discovery and optimization of the first inhibitor of human and rat sEH-P that is applicable in vivo. X-ray structure analysis of the sEH phosphatase domain complexed with an inhibitor provides insights in the molecular basis of small-molecule sEH-P inhibition and helps to rationalize the structure-activity relationships. 4-(4-(3,4-Dichlorophenyl)-5-phenyloxazol-2-yl)butanoic acid (22b, SWE101) has an excellent pharmacokinetic and pharmacodynamic profile in rats and enables the investigation of the physiological and pathophysiological role of sEH-P in vivo.

The present invention provides a kind of atorvastatin key intermediate of environmental protection preparation method, the intermediate body is 4 - fluoro - alpha - [2 - methyl - 1 - oxygen propyl] - gama - oxo - N, beta - diphenyl benzene ding amide, the method uses hydrogen peroxide oxidation of an alkali metal salt of bromide, bromine generated in-situ, brominated 4 '- fluorophenyl - 2 - acetophenone synthesis of 2 - bromo - 1 - (4' - fluoro phenyl) - 2 - acetophenone; above brominated alkali metal salt can be the recovery of the condensation reaction by-product, the obtained 2 - bromo - 1 - (4' - fluoro phenyl) - 2 - acetophenone with isobutyryl acetyl aniline under the action of the acid condensation reaction to obtain the target product, 4 - fluoro - alpha - [2 - methyl - 1 - oxygen propyl] - gama - oxo - N, beta - diphenyl benzene ding amide. When the condensation reaction to form a brominated alkali metal salt recovery, is used for the next batch 4' - fluorophenyl - 2 - acetophenone of the bromination reaction. The method epihalogenohydrine atomic access to fully recycle, greatly reduce the emission of halogen-containing waste. The utilization rate of higher than 80%, saving, full use of resources, reduce environmental pollution, truly environmental protection.
