N-[2-(2-Hy­droxy­eth­oxy)pheneth­yl]phthalimide

The title compound, C₁₈H₁₇NO₄, was obtained accidentally through acid-catalysed aromatization of a phthalimide-substituted 2-(1-hy­droxy­eth­yl)cyclo­hex-2-enone. It exhibits an intra­molecular O—H...O_c (c = carbonyl) hydrogen bond and forms a three-dimensional network structure via π–π stacking inter­actions between adjacent benzene rings (phthalimide-to-phenyl­ene and phthalimide-to-phthalimide), with centroid–centroid distances of 3.8262 (6) and 3.6245 (5) Å.
