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.
Asymmetric methylation and phenylation of the chiral pyridinium salt 7, as well as methylation of chiral pyridinium salt 18, with Grignard reagents occurred in good yield and with good-to-excellent diastereoselectivities (Schemes 2 and 3, resp.). These results are best explained by assuming chelate control to govern the asymmetric alkylation/arylation process. The minimum-energy conformations of the
