(Arylthio)benzoic acids IIa - IIe and VIb - VId were transformed via the acid chlorides to the N,N-dimethylamides which were reduced either with diborane "in situ" or with lithium aluminium hydride to N,N-dimethyl-(arylthio)benzylamines Ia - Ie and Vb - Vd. Leuckart reaction of the aldehydes IX and X with dimethylformamide and formic acid afforded directly the amines Va and Ve. Demethylation of the methoxy compounds Ia and Ve with hydrobromic acid resulted in the phenolic amines If and Vf. The most interesting N,N-dimethyl-4-(phenylthio)benzylamine (Va) hydrochloride showed affinity to cholinergic and 5-HT2 serotonin receptors in the rat brain and some properties considered indicative of antidepressant activity (inhibition of serotonin re-uptake in the brain and potentiation of yohimbine toxicity in mice).
苯硫基苯甲酸IIa - IIe和VIb - VId经过酸氯化物转化为N,N-二甲酰胺,然后通过硼氢化钠或氢化铝锂还原为N,N-二甲基-(苯硫基)苄胺Ia - Ie和Vb - Vd。利用二甲基甲酰胺和甲酸的Leuckart反应直接合成胺Va和Ve。对甲氧基化合物Ia和Ve进行脱甲基化处理,得到酚胺If和Vf。最有趣的N,N-二甲基-4-(苯硫基)苄胺(Va)盐酸盐在大鼠脑组织中显示出对胆碱能和5-HT2 5-羟色胺受体的亲和力,以及一些被认为具有抗抑郁活性的特性(抑制脑内5-羟色胺再吸收和增强对鹰木毒素在小鼠体内的毒性)。
