Abstract
In the title compound, C17H21N3O, the C—N bond lengths in the guanidine unit are 1.2889 (19), 1.3682 (19) and 1.408 (2) Å, indicating double- and single-bond character. The N—C—N angles are 115.10 (13), 119.29 (15) and 125.61 (14)°, showing a deviation of the CN3 plane from an ideal trigonal–planar geometry. In the crystal, non-classical C—H⋯O hydrogen bonds between methyl H atoms and methoxy O atoms are present, generating centrosymmetric dimers running in the [101] direction.

calculated positions with (C—H) O hydrogen bonds between methyl H atoms and methoxy O atoms are present, generating centrosymmetric dimers running in the [101] direction
R-factors based on F2 are statistically about twice as large as those based on F, and R-factors based on ALL data will be even larger
