The asymmetric unit of the title compound, C15H16N2·C4H8O, contains two amidine mol-ecules (A and B) with slightly different conformations and two tetra-hydro-furan (THF) solvent mol-ecules. In the amidine mol-ecules, the di-methyl-phenyl ring and the NH2 group lie to the same side of the N=C bond and the dihedral angles between the aromatic rings are 54.25 (7) (mol-ecule A) and 58.88 (6) ° (mol-ecule B). In the crystal, N-H⋯N hydrogen bonds link the amidine mol-ecules into [100] C(4) chains of alternating A and B mol-ecules. Both amidine mol-ecules form an N-H⋯O hydrogen bond to an adjacent THF solvent mol-ecule.
