The preparation of compounds having the formula I ##STR1## where R.sup.1 is --CN, --CO--N(CH.sub.3).sub.2 or --CS--N(CH.sub.3).sub.2 and R.sup.2 is hydrogen, methyl or a removable protecting group is carried out by condensing a compound having the formula ##STR2## where M is lithium, sodium, potassium or halomagnesium and R.sup.3 is methyl or a removable protecting group in a solvent comprising 80-100% of one or more hydrocarbons and 0-20% of one or more ethers. The solvent enables less inconvenient reaction temperatures to be used and higher yields to be obtained. Compounds (I) are new per se where R.sup.1 is --CS--N(CH.sub.3).sub.2. Compounds (I) are chemical intermediates for preparing N,N-dimethyl-2-(1-hydroxycyclohexyl)-2-(4-hydroxyphenyl or 4-methoxyphenyl) ethylamine and pharmaceutically acceptable salts thereof. These end products are antidepressants.
具有以下式I的化合物的制备##STR1##其中R.sup.1为--CN,--CO--N(CH.sub.3).sub.2或--CS--N(CH.sub.3).sub.2,R.sup.2为氢,甲基或可去除的保护基团,通过将具有以下式##STR2##的化合物与M为
锂,
钠,
钾或卤化
镁,R.sup.3为甲基或可去除的保护基团的化合物在溶剂中进行缩合来实现。所述溶剂包括80-100%的一个或多个碳氢化合物和0-20%的一个或多个醚。该溶剂使得可以使用更少不便的反应温度并获得更高的产率。其中R.sup.1为--CS--N(CH.sub.3).sub.2时,化合物(I)本身是新的。化合物(I)是制备N,N-二甲基-2-(1-羟基环己基)-2-(
4-羟基苯基或4-
甲氧基苯基)
乙胺及其药用可接受盐的
化学中间体。这些最终产品是抗抑郁药物。
