Claims (1)
구조식(Ⅲ)의 화합물을 디아조화 반응을 시킨 후, 구조식(Ⅳ)의 화합물과 반응시켜 O.S-디티오카보네이트 유도체인 구조식(Ⅴ)의 화합물을 제조하고 이를 피리딘 유도체인 구조식(Ⅵ)의 화합물과 반응시켜 구조식(Ⅱ)의 화합물을 제조한 후 산화시킴을 특징으로 하는 구조식(I)로 표현되는 벤즈이미다졸 유도체의 제조방법.The compound of formula (III) is subjected to a diazotization reaction, and then reacted with the compound of formula (IV) to prepare a compound of formula (V), which is an OS-dithiocarbonate derivative, and the compound of formula (VI) which is a pyridine derivative. A method for producing a benzimidazole derivative represented by formula (I) characterized by reacting to produce a compound of formula (II), followed by oxidation.(상기 구조식에서 R은 탄소수 1-7인 알킬기이다.)(Wherein R is an alkyl group having 1-7 carbon atoms)※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
