N-[2-(3-Methyl-1-oxo-1,2-dihydropyrrolo[1,2-a]pyrazin-2-yl)ethyl]methanesulfonamide

Abstract

In the title compound, C11H15N3O3S, the dihedral angle between the five- and six-membered rings is 1.13 (18)°. The ethylmethanesulfonamide group is in a (+)synclinal conformation. In the crystal, intermolecular N—H...O and C—H...O hydrogen-bond interactions link molecules into zigzag ribbons parallel to the b axis. The ribbons are further connected by C—H...π interactions.
