| titleOfInvention | Method for preparing dioxolane derivatives |
| abstract | The present invention provides 4- [4-4- [2-Ar-2 (1H-azol-1-ylmethyl) -1,3-dioxolan-4-ylmethoxy] phenyl] piperazine of the general formula (A) It relates to a method for producing a derivative.n n n According to the present invention, the final target compound of formula (I) is prepared by reacting a piperazine derivative of formula (II) with an imidazole derivative of formula (III) under an acid catalyst, wherein the piperazine compound of formula (II) Is prepared by forming a metal salt of formula (V) using a metal alkoxide or the like followed by reaction with an oxylene derivative of formula (VI).n n n n n n n n n n n n n Wherein Ar is a phenyl group optionally substituted with up to 3 halogen elements, M is Na or K, and X represents Cl or Br.n n n The present invention provides a novel production method for preparing the target compound (A) with high yield and high purity, and is an efficient and economical method for securing the intermediate, simple process and very high reactivity. |
