| titleOfInvention | Method for preparing a conjugated ring pyridine derivative containing oxygen |
| abstract | The present invention relates to a method for preparing a conjugated ring pyridine derivative containing oxygen, and more particularly, by reacting dihalopyridine represented by the following structural formula (II) with sodium alkoxylate containing a double bond, the following structural formula (III) A conjugated pyridine derivative containing oxygen represented by the following structural formula (I), which is useful as an intermediate of various pharmaceutical products, is prepared by preparing a halo-alkoxypyridine represented by It relates to a manufacturing method.n n n n n n n n n n n n n In the above formula,n n n n n n n n hal. is a halogen atom; R is a C 3 to C 6 alkenyl group containing a double bond; Y is a hydrogen atom, a halogen atom, a cyano group or a C 1 -C 3 alkyl group;n n n n n n n n In this case, R 1 , R 2 , R 3 , R 4 , R 5 and R 6 are the same or different from each other and are a hydrogen atom or a C 1 to C 4 linear or pulverized alkyl group. |
