An object of the present invention is to provide a method for reproducibly producing a pyrrolopyrimidine ring-containing tricyclic compound in high yield with reduced formation of by-products, and to provide a novel tricyclic compound capable of being obtained by this production method. The present invention provides a method for producing a compound represented by Formula (1) or a salt thereof, the method comprising the steps of: (I) causing an organic borane reagent to act on a compound represented by Formula (2) or a salt thereof, and (II) performing an intramolecular cyclization reaction of the reaction product of step (I) above using a zerovalent palladium catalyst in the presence of an alkali metal hydroxide.
本发明的目的是提供一种方法,以高收率可重复地生产含有吡咯吡嘧啶环的三环化合物,并减少副产物的形成,并提供一种能够通过这种生产方法获得的新型三环化合物。本发明提供了一种制备由式(1)或其盐所表示的化合物的方法,该方法包括以下步骤:(I)使有机硼试剂作用于由式(2)或其盐所表示的化合物,和(II)在碱金属氢氧化物存在下,使用零价钯催化剂对步骤(I)中的反应产物进行分子内环化反应。
