The present invention relates to a process for the preparation of azaindole derivatives of the formula ##STR1## wherein Q is hydrogen, C.sub.1-6 alkyl, C.sub.2-6 alkenyl, C.sub.1-6 alkoxy, hydroxy, aryl or arylC.sub.1-4 alkyl; one of X, Y and Z is --N.dbd. and the others are --CH.dbd.; R.sup.1 is hydrogen, C.sub.1-6 alkyl, C.sub.2-6 alkenyl or C.sub.1-6 alkyl substituted by a group selected from aryl or --NR.sup.2 R.sup.3 where R.sup.2 and R.sup.3 each independently represent C.sub.1-4 alkyl, or R.sup.2 and R.sup.3, together with the nitrogen atom to which they are attached, form a 4-7 membered saturated heterocyclic ring, optionally containing in the ring an oxygen or sulphur atom or a group NR.sup.4 where R.sup.4 is C.sub.1-4 alkyl, aryl or arylC.sub.1-4 alkyl; and R.sup.5 is a hydrogen atom or a group selected from C.sub.1-6 alkyl or aryl.
本发明涉及一种制备式为##STR1##的氮杂吲哚衍生物的方法,其中Q为氢、C.sub.1-6烷基、C.sub.2-6烯基、C.sub.1-6烷氧基、羟基、芳基或芳基C.sub.1-4烷基;X、Y和Z中的一个是--N.dbd.,其余为--CH.dbd.;R.sup.1为氢、C.sub.1-6烷基、C.sub.2-6烯基或C.sub.1-6烷基,被芳基或--NR.sup.2R.sup.3所取代,其中R.sup.2和R.sup.3各自独立地代表C.sub.1-4烷基,或R.sup.2和R.sup.3与它们所连接的氮原子一起形成一个4-7成员饱和杂环,选项包括在环中含一个氧或硫原子或一个NR.sup.4基团,其中R.sup.4为C.sub.1-4烷基、芳基或芳基C.sub.1-4烷基;R.sup.5为氢原子或选自C.sub.1-6烷基或芳基的基团。
