There is described a process for the preparation of compounds of formula I
in which
R is hydrogen, optionally substituted alkyl, optionally substituted alkenyl optionally substituted cycloalkyl, optionally substituted phenyl or optionally substituted heterocyclyl, and
R1 and R2 are hydrogen, an organic radical or together with the ring to which they are attached, form an optionally substituted ring, which may contain one or more hetero atoms,
which comprises reacting a compound of formula II
with a compound of formula III
in which the ring Q is an optionally substituted heteroaromatic ring, which optionally comprises one or more further hetero atoms and to which is optionally fused an optionally substituted ring.
描述了一种制备公式I化合物的过程,其中R是氢、可选择地取代的烷基、可选择地取代的烯基、可选择地取代的环烷基、可选择地取代的苯基或可选择地取代的杂环基;R1和R2是氢、有机基或与它们所附着的环一起形成可选择地取代的环的情况,该环可能含有一个或多个杂原子,包括将公式II化合物与公式III化合物反应,其中环Q是可选择地取代的杂芳香环,可能包含一个或多个进一步的杂原子,并且可选择地融合一个可选择地取代的环。
