Abstract: In the title compound, C₁₂H₁₅NO₃, the isoquinoline moiety is essentially planar, except for the N and adjacent Csp³ atoms, which deviate from the mean plane by 0.198  (2) and 0.686  (2)  Å, respectively. The bond length between the N and carbonyl C atoms [1.353  (3)  Å] is close to a double-bond value, indicating electron delocalization. No significant intermolecular interactions are observed.
