In the title mol-ecule, C14H15NO3, the ring system is essentially planar, with an r.m.s. deviation of 0.003 Å. The atoms of the ethane-1,2-diol group were refined as disordered over two sets of sites in a ratio of 0.815 (3):0.185 (3). The mol-ecular conformation is stabilized in part by an intra-molecular N-H⋯O hydrogen bond, which forms an S(6) ring. In the crystal, mol-ecules are connected by...
