본문에 상술한 바와 같이 테트라하이드로푸란과 디옥산의 95∼90:5∼10혼합용매내에 포스겐 가스를 용해시킨후 포스겐을 드라이아이스 아세톤 콘덴서를 사용하여 환류시키면서 3,4-디할로 아닐린을 첨가하여 다음 구조식(Ⅱ)의 물합물을 제조한 다음 정제하지 않고 직접 90:10의 테트라하이드로 푸란과 디옥산의 혼합 용매내에서 구조식(Ⅲ)의 화합물과 구조식(Ⅲ)의 화합물을 40∼45℃하에 반응 시킴을 특징으로 하는 다음 구조식(Ⅰ)로 표시되는 할로 카바닐리드의 제조방법.As described above, dissolve the phosgene gas in a 95 to 90: 5 to 10 mixed solvent of tetrahydrofuran and dioxane, and then add 3,4-dihaloaniline while refluxing the phosgene using a dry ice acetone condenser. A mixture of the following formula (II) was prepared, and then the mixture of the formula (III) and the compound of the formula (III) in a mixed solvent of tetrahydrofuran and dioxane (90:10) was purified without purification at 40 to 45 ° C. A process for preparing halo carbanilide represented by the following structural formula (I) characterized by reaction.상기 구조식에서, X₁,X₂및 X₃는 같거나 서로 다른 할로겐 원자를 나타낸다.In the above structural formula, X₁, X2 and X₃ represent the same or different halogen atoms.※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
