7-Acetylamino-2,4-dimethyl-1,8-naphthyridine

Abstract

The air-stable title compound, C12H13N3O, which is of interest due to its antibacterial properties, is an almost planar molecule in which the ten atoms forming the 1,8-naphthyridine ring have an r.m.s. deviation of 0.03 Å from the least-squares plane calculated using the ten atoms. The plane of the acetylamino group is slightly inclined [11.7 (2)°] to the plane of the 1,8-naphthyridine ring.
