Abstract: A method for preparing heterocyclic halide of formula (I), (II) and (III) comprises a diamino-substitution reaction of heterocyclic primary amine with CuCl2 (or CuBr2) and t- butylthionitrite (t-BuSNO) or t-butylthionitrate (t-BuSNO2) in an organic solvent. In the formulas, X=Cl or Br; R= benzyl or ribose. Pref. the molar ratio of heterocyclic primary amine:CuCl2 (or CuBr2):t-BUSNO (or t-BuSNO2) is 1:2:2.
Abstract translation: 制备式(I),(II)和(III)的杂环卤化物的方法包括杂环伯胺与CuCl 2(或CuBr 2)和叔丁基硫代亚硝酸酯(t-BuSNO)或硫酸叔丁酯(t)的二氨基取代反应 -BuSNO2)在有机溶剂中。 在式中,X = Cl或Br; R =苄基或核糖。 县。 杂环伯胺:CuCl 2(或CuBr 2):t-BUSNO(或t-BuSNO 2)的摩尔比为1:2:2。

Abstract: The title compds. of formula RC(OH)CONHAr are prepd. by reacting N- sulfinylamine of formula Ar-N=S=O with RC(OH)COOH in an org. solvent i.e. acetonitrile, benzene, THF., where Ar=Ph, pchlorophenyl, R=H, - COOH, -HCOH, Ph. Thus, dissolve 2-hydroxybutanoic acid (230mg) in acetonitrile (10ml), add N-sulfinylaniline (280mg) and stir for 6hr at room temp., eliminate solvent and recrystg. in water/EtOH to give N-phenyl-2-hydroxy butanamide 340mg (96%).
Abstract translation: 标题compds。 的式RC(OH)CONHAr是制备的。 通过使式Ar-N = S = O的N-亚磺酰胺与组分中的RC(OH)COOH反应。 溶剂即乙腈,苯,THF,其中Ar = Ph,对氯苯基,R = H,-COOH,-HCOH,Ph。因此,将2-羟基丁酸(230mg)溶于乙腈(10ml)中,加入N-亚磺酰苯胺(280mg )并在室温下搅拌6小时,消除溶剂并重结晶。 在水/ EtOH中,得到N-苯基-2-羟基丁酰胺340mg(96%)。
