摘要:
The present invention relates to a preparation method of 2-thioxo furopyrimidin-4-one represented by chemical formula 1 and an intermediate product used thereto. More particularly, the preparation method of the present invention obtains a thiourea carboxylate derivative represented by chemical formula 2 by having a reaction of a compound represented by chemical formula a with benzoyl isothiocyanate, and obtains the 2-thioxo furopyrimidin-4-one represented by chemical formula 1 by having a cyclization reaction of the compound represented by chemical formula 2 in presence of a base. The compound represented by chemical formula 1 can be useful as an intermediate product in preparing a medicine such as an anticancer drug, or the like.COPYRIGHT KIPO 2016본 발명은 화학식 a의 화합물을 벤조일 아이소싸이오시아네이트와 반응시켜 화학식 2의 싸이오우레아 카르복실레이트 유도체를 수득하고, 수득한 화학식 2의 화합물을 염기 존재하에 고리화 반응시켜 화학식 1의 2-싸이옥소 퓨로피리미딘-4-온 화합물을 제조하는 방법 및 이에 사용되는 중간체에 관한 것으로서, 화학식 1의 화합물은 항암제 등의 의약품 제조에 있어 유용한 중간체로 사용할 수 있다.
