4-Chloro-N-(pyrazin-2-yl)aniline
In the title compound, C(10)H(8)ClN(3), the dihedral angle between the aromatic rings is 43.0 (1)° and the bridging C-N-C angle is 128.19 (16)°. The amino N atom of one mol-ecule forms a hydrogen bond to the 1-N atom of an adjacent pyrazinyl ring, generating an inversion dimer.

In the title compound, C(18)H(21)N(3)O(2), the dihedral angle between the phenyl and benzene rings is 36.85 (10)°. The methyl C atom of one of the ethyl groups is disordered over two positions with site occupancies of 0.810 (8) and 0.190 (8). The mol-ecular structure is stabilized by a classical intra-molecular O-H⋯N hydrogen bond. The crystal structure exhibits weak inter-molecular N-H⋯O, C-H⋯...

In the title compound, C(11)H(15)N(3)O(3)S, the dihedral angle between the five- and six-membered rings is 1.13 (18)°. The ethyl-methane-sulfonamide group is in a (+)synclinal conformation. In the crystal, inter-molecular N-H⋯O and C-H⋯O hydrogen-bond inter-actions link mol-ecules into zigzag ribbons parallel to the b axis. The ribbons are further connected by C-H⋯π inter-actions.
