✦ Synopsis
In the crystal structure of the title compound, C 14 H 17 NO 3 , intermolecular O-HÁ Á ÁO hydrogen bonds [OÁ Á ÁO = 2.692 (4) A ˚] link the molecules into extended one-dimensional chains. These chains are, in turn, linked into a threedimensional network by weak intermolecular C-HÁ Á ÁO interactions [CÁ Á ÁO = 3.368 (5) A ˚].
