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.
