Abstract
본 발명은 피리딘 유도체 산화 방법에 관한 것이다.The present invention relates to a method of oxidizing pyridine derivatives.
일반식(Ⅰ)의 피리딘 화합물을 초산 용매하에서 과산화 수소로 산화시켜 일반식(Ⅱ)의 피리딘-N-옥사이드 화합물을 제조할 때, 잔류하는 과산화수소의 파괴방법으로 황산-황산바륨 완충용액과 이소프로필 알콜을 첨가하므로서, 폭발위험성이 제거되고 고순도 및 고수유로 제조할 수 있는 방법으로서, 반응조작이 간편한 장점이 있다.When the pyridine compound of formula (I) is oxidized with hydrogen peroxide in a solvent of acetic acid to prepare a pyridine-N-oxide compound of formula (II), the method of destroying the residual hydrogen peroxide and the barium sulfate buffer solution and isopropyl By adding alcohol, the explosion hazard is eliminated and can be manufactured with high purity and high lactation.
상기식중 R,R1은 H 또는 CH3이다.Wherein R, R 1 is H or CH 3 .
