followed by reaction with thionyl chloride, into α-fluorophenylacetyl chloride (not isolated) and thence into the corresponding amide or NN-dimethylamide by conventional reactions. Diborane reduced the NN-dimethylamide to NN-dimethyl-2-fluoro-2-phenylethylamine (53%), also obtained by the action of dimethylamine on 1-bromo-2-fluoro-2-phenylethane. Reduction of the NN-dimethylamide with lithium aluminium
无水氟化钾和乙基α溴苯在NN二甲基甲酰胺在145-150°,得到相应的α氟酯(53%),将其通过碱性水解和酸化转化,随后用亚硫酰氯反应,变成α氟苯基乙氯化物(未分离),然后通过常规反应转化为相应的酰胺或NN-二甲基酰胺。乙硼烷减少NN -dimethylamide到NN二甲基-2-氟-2-苯乙胺(53%),也由二甲胺的动作上的1-溴-2-氟-2-苯基乙烷而获得。用氢化锂铝在乙醚中还原NN-二甲基酰胺,得到产物混合物。
