The present invention provides a process for preparing 1,2-diheteroethylene sulfonamide of the formula: ##STR1## by reacting a pyrimidine monohalide of the formula: ##STR2## with a mono-protected 1,2-diheteroethylene anion of the formula M.sub.1 XCH.sub.2 CH.sub.2 YR.sub.5 and removing the protecting group, wherein R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5, R.sub.6, R.sub.7, R.sub.8, R.sub.9, Z, X, Y, M, M.sub.1 and W are defined herein.
本发明提供了一种制备式为:##STR1##的1,2-二杂乙烯磺酰胺的方法,该方法通过将式为:##STR2##的嘧啶单卤代物与式为M.sub.1 XCH.sub.2 CH.sub.2 YR.sub.5的单保护1,2-二杂乙烯负离子反应,并去除保护基,其中R.sub.1,R.sub.2,R.sub.3,R.sub.4,R.sub.5,R.sub.6,R.sub.7,R.sub.8,R.sub.9,Z,X,Y,M,M.sub.1和W在此被定义。
