| titleOfInvention | A kind of preparation method of 1-[(4-chlorphenyl) methyl]-2-oxo-cyclopentane formic acid esters |
| abstract | The invention discloses the preparation method of a kind of 1 [(4 chlorphenyl) methyl] 2 oxo-cyclopentane formic acid esters, comprise the steps: to add alkali carbonate or alkaline earth metal carbonate in aprotic solvent, one in 2 oxo-cyclopentane methyl formates and 2 oxo-cyclopentane Ethyl formates and 4 chlorobenzyl chlorides are added in described aprotic solvent, stirring, under iodide are catalyzed, normal heating back flow reaction 8～36 hours, after having reacted, product is filtered, after gained filtrate Distillation recovery aprotic solvent, obtain end product；In described end product, the purity of 1 [(4 chlorphenyl) methyl] 2 oxo-cyclopentane formic acid esters is more than 95%, and yield is higher than 95%.Described preparation method reaction condition is gentle, simple to operate, it is high to prepare product yield, purity is high, is conducive to carrying out industrialized production. |
