The present invention provides aromatic nitrogen-containing 6-membered ring compounds having execellent PDE10 inhibitory activity. The present invention relates to an aromatic nitrogen-containing 6-membered ring compound represented by the following formula [I0] or a pharmaceutically acceptable salt thereof, a method for preparing the same, and use of said compounds for PDE10 inhibitors, and a pharmaceutical composition comprising said compounds as an active ingredient: Formula [I0] wherein: X1, X2 and X3 each independently are N or CH, and at least two of X1, X2 and X3 are N; A is *-CH=CH-, *-C(Alk)=CH-, *-CH2-CH2- or *-O-CH2- (* is a bond with R1); Alk is a lower alkyl group; Ring B is an optionally substituted nitrogen-containing aliphatic heterocyclic group; R1 is an optionally substituted nitrogen-containing heterocyclic group, a nitrogen-containing heterocyclic moiety of which is a moiety selected from the group consisting of quinoxalinyl, quinolyl, isoquinolyl, quinazolinyl, pyrazinyl, pyrimidinyl and a moiety thereof fused with a 5 to 6-membered aliphatic ring thereto; Y0 is a group selected from the group consisting of the following (1) to (5): (1) an optionally substituted phenyl or an optionally substituted aromatic monocyclic 5 to 6-membered heterocyclic group; (2) an optionally substituted aminocarbonyl; (3) an optionally substituted amino lower alkyl; (4) -O-R2 wherein R2 is hydrogen, an optionally substituted lower alkyl, lower cycloalkyl, aliphatic monocyclic 5 to 6-membered heterocyclic group, or Formula [AA]; (5) mono- or di-substituted amino; provided that, when Y0 is mono- or di-substituted amino, the nitrogen-containing heterocyclic moiety of R1 is not quinoxalinyl or quinolyl.
