The novel method of synthesis of sulphonamide derivatives (I), comprising reaction of alkyl-4-halophenylsulfonate with an amine. Formula (I) wherein X is halogen and R1 and R2 are independently selected from group comprising (i) C1 to C15 alkyl, straight or branched, (ii) C3 to C15 cycloalkyl, substituted or unsubstituted, (iii) C2 to C15 alkenyl, straight or branched, (iv) C2 to C15 alkynyl, straight or branched, (v) phenyl or benzyl, substituted or unsubstituted, (vi) heterocycloalkyl, substituted or unsubstituted, (vii) hydrogen, (viii) form with the nitrogen to which they are attached a 3-7 membered heterocyclic moiety such as pyrolidine, piperidine, piperazine, imidazole, pyrazole, (ix) the alkyl in i) may be attached to a moiety selected from cycloalkyl or heterocycloalkyl, substituted or unsubstituted
合成磺胺衍生物的新方法(I),包括烷基-4-卤苯磺酸酯与胺反应。公式(I)中X为卤素,R1和R2分别选自以下组:(i)C1到C15烷基,直链或支链,(ii)C3到C15环烷基,取代或未取代,(iii)C2到C15烯基,直链或支链,(iv)C2到C15炔基,直链或支链,(v)苯基或苄基,取代或未取代,(vi)杂环烷基,取代或未取代,(vii)氢,(viii)与它们连接的氮形成3-7个成员的杂环基团,如吡咯烷,哌啶,哌嗪,咪唑,吡唑,(ix)i)中的烷基可以连接到取代或未取代的环烷基或杂环烷基的基团上。
