Abstract
본 발명은 항진균제로 유용한 다음 일반식( I )로 표시되는 트리아졸 유도체, 그의 입체 이성질체 및 그의 약제학적으로 허용되는 산부가염을 제조하는 방법에 관한 것으로, 불활성 유기용매와 알칼리금속 염기 존재하, 다음 일반식(Ⅲ)로 표시되는 트리아졸 페닐 피페라진 페놀 유도체를 일반식(V)로 표시되는 18-크라운-6과 같은 크라운 에테르(Crownether)를 촉매로 사용하여 일반식(Ⅱ)로 표시되는 아졸 유도체와 반응시켜서 목적화합물을 제조한다.The present invention relates to a process for preparing triazole derivatives represented by the following general formula (I), useful as antifungal agents, stereoisomers thereof and pharmaceutically acceptable acid addition salts thereof, in the presence of an inert organic solvent and an alkali metal base, Azole represented by formula (II) using a triazole phenyl piperazine phenol derivative represented by formula (III) as a catalyst using a crown ether such as 18-crown-6 represented by formula (V) as a catalyst Reaction with a derivative yields the desired compound.
상기 식에서, B는 CH또는 N이며, Ar은 할로겐 및 메톡시기로 구성된 군에서 독립적으로 선택된 1개 또는 2개의 라디칼로 임의로 치환된 페닐기이며, R1은 수소, C1-4의 저급알킬 또는 아릴알킬이며, X는 할로겐, 메탈설포닐옥시 또는 4-메틸벤젠설포닐옥시 등의 설폰산기 같은 반응성 에스테르잔기이며, Y는 수소 또는 알칼리금속 즉, 소디움, 칼륨, 바륨 또는 세슘 등이며, M은 소디움, 칼륨, 바륨 또는 세슘등의 알칼리 금속이고, Z는 하이드록시기, 탄산영, 메톡시, 에톡시, t-부톡시 또는 수소 등이고, R2는 및 R3는 서로 같거나 다를 수 있으며, 알킬, 헥실, 페닐 또는 벤조일기이고, n은 4-8의 정수로 폴리에테르환을 이룬다.Wherein B is CH or N, Ar is a phenyl group optionally substituted with one or two radicals independently selected from the group consisting of halogen and methoxy groups, R 1 is hydrogen, lower alkyl or aryl of C 1-4 Alkyl, X is a reactive ester residue such as a sulfonic acid group such as halogen, metalsulfonyloxy or 4-methylbenzenesulfonyloxy, Y is hydrogen or an alkali metal such as sodium, potassium, barium or cesium, and M is sodium , An alkali metal such as potassium, barium or cesium, Z is a hydroxy group, carbonate, methoxy, ethoxy, t-butoxy or hydrogen, etc., R 2 and R 3 may be the same or different from each other, alkyl , Hexyl, phenyl or benzoyl group, n forms a polyether ring with an integer of 4-8.
본 발명은 새로운 방법에 의해 개발된 카폴링(coupling)효과가 우수한 촉매로 크라운 에테르를 이용함으로써 현재 가동중인 공정을 살릴 수 있을 뿐만 아니라, 종래의 기술에 비해 온화한 반응온도, 짧은 시간, 높은 수율로 목적화합물을 제조할 수 있다.The present invention not only saves the current process by using the crown ether as a catalyst having excellent coupling effect developed by the new method, but also has a mild reaction temperature, short time, and high yield compared to the prior art. The desired compound can be prepared.
