N-tert-Butyl-2-[4-(dimethyl-amino)-phen-yl]imidazo[1,2-a]pyrazin-3-amine.

In the title compound, C18H23N5, the imidazole ring makes a dihedral angles of 3.96†(8) and 19.02†(8)°, respectively, with the pyrazine and benzene rings while the dihedral angle between the pyrazine and benzene rings is 16.96†(7)°. In the crystal, mol-ecules are linked via N-H⋯N hydrogen bonds, forming chains along [010]. These chains are linked by C-H⋯N hydrogen bonds, forming two-dimensional networks lying parallel to (001).
