A highly efficient and general solid-phase synthesis of bicyclic pyrimidine derivatives that target purine dependent proteins is reported. The synthesis of the key intermediate, 4,6-disubstituted-5-amino-pyrimidine, involved reduction of the corresponding nitro derivatives using 1,1'-dioctyl-viologen in a triphasic milieu. The mild reduction conditions enable the use of any acid labile solid support
The present invention provides: a novel use of a specific bicyclic nitrogen-containing heterocyclic compound as a PDE7 inhibitor; a novel bicyclic nitrogen-containing heterocyclic compound having a PDE7 inhibitory effect, a method for producing the compound, a use of the compound, and a pharmaceutical composition containing the PDE7 inhibitor or the compound; and others. More specifically, the present invention provides a PDE7 inhibitor containing the compound represented by the formula (I):
[wherein the symbols have the same meanings as those described in the description] or a pharmaceutically acceptable salt thereof as an active ingredient.
