A process for preparing a halogenoalkylsulfonamide derivative represented by the general formula (I):
wherein R1 is alkyl, hydroxyalkyl, cycloalkyl, or phenyl which may have alkyl, alkoxy, halogen, hydroxyl, trifluoromethyl, nitro and amino; R2 is hydrogen atom, alkyl, hydroxyalkyl, cycloalkyl, or phenyl which may have alkyl, alkoxy, halogen, hydroxyl, trifluoromethyl, nitro and amino; X is chlorine, bromine or iodine; and Y is alkylene group having 5 to 12 carbon atoms; an intermediate; and a process for preparing the intermediate. The amide derivative is a useful compound as an intermediate for preparing a diazacycloalkanealkylsulfonamide derivative, which has antiallergic activity and thereby is useful as a medicament for preventing and treating diseases such as bronchial asthma, allergic rhinitis, atopic dermatitis, urticaria, and the like.
一种制备一种由通式(I)表示的卤代烷基磺酰胺衍生物的方法:其中R1是烷基,羟基烷基,环烷基或苯基,可能具有烷基,烷氧基,卤素,羟基,三氟甲基,硝基和氨基;R2是氢原子,烷基,羟基烷基,环烷基或苯基,可能具有烷基,烷氧基,卤素,羟基,三氟甲基,硝基和氨基;X是氯,溴或碘;Y是具有5至12个碳原子的烷基基团;一种中间体;以及制备该中间体的方法。酰胺衍生物是一种有用的化合物,可作为制备二氮杂环烷基磺酰胺衍生物的中间体,具有抗过敏活性,因此可用作预防和治疗支气管哮喘、过敏性鼻炎、特应性皮炎、荨麻疹等疾病的药物。
