N-[2-(3-Methyl-1-oxo-1,2-dihydro-pyrrolo-[1,2-a]pyrazin-2-yl)eth-yl]methane-sulfonamide

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 ribbon...

Description
Summary: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.
