Abstract

The title compound, C14H21NO4, has been synthesized from o-dihydroxy­benzene by a three-step reaction. There are two chemically equal but crystallographically independent mol­ecules in the asymmetric unit. The crystal packing is governed by C—H⋯O hydrogen bonds and C—H⋯π inter­actions, forming an infinite network.
