An efficent synthesis of furan sulfonamide compounds of formula
comprising reacting a compound of formula II with a Grignard reagent in a reaction inert solvent, wherein R' is (C1-C6)alkyl. The compound of formula II is prepared by reacting a compound of formula III with a compound of formula IV wherein R' is (C1-C6)alkyl with a chorinating reagent and an acid scaverger in an inert solvent. The invention also includes a novel compound of the formula
wherein R' is (C1-C6)alkyl and Q is halo, hydroxy or amino.
一种有效的合成呋喃磺酰胺化合物的方法,包括在反应惰性溶剂中,将式II化合物与Grignard试剂反应,其中R'为(C1-C6)烷基。式II化合物是通过在惰性溶剂中,将式III化合物与式IV化合物反应而制备的,其中R'为(C1-C6)烷基,使用氯化试剂和酸性清除剂。该发明还包括一种新的化合物,其化学式为,其中R'为(C1-C6)烷基,Q为卤素、羟基或氨基。
