    In the title compound, C22H17N5·CH4O, the imidazolidine ring of the 1,2,3,5,6,7-hexahydroimidazo[1,2-a]pyridine ring system is a twisted envelope, while the 1,2,3,4-tetrahydropyridine ring adopts a twisted boat conformation. In the crystal, pairs of molecules are linked by O—H?N and N—H?O hydrogen bonds via two methanol molecules, forming a centrosymmetric R44(16) ring motif. These motifs are connected to each other by C—H?N hydrogen bonds and form columns along the a axis. The columns form a stable molecular packing, being connected to each other by van der Waals interactions. A Hirshfeld surface analysis indicates that the most significant contributions to the crystal packing are from H?H (43.8%), N?H/H?N (31.7%) and C?H/H?C (18.4%) contacts.
