The title compound, C 17 H 19 NO 4 , was synthesized by the Stobbe condensation reaction of p-dimethylaminobenzaldehyde and diethyl succinate, followed by cyclization of the Stobbe product. The crystal structure is stabilized by intermolecular C-HÁ Á Á interactions.

✦ Synopsis
A sample of ethyl 6-methoxy-2-naphthoate was obtained from Strides Arco Labs, Mangalore, India. Colourless plates of (I) were obtained by slow evaporation using a mixture (1:1 v/v) of acetone and toluene (m.p.: 359-361 K).
Refinement
The H atoms were found in a difference map, relocated in idelised loations (C-H = 0.95-0.99 Å), and refined as riding with U iso (H) = 1.2U eq (C) or U iso (H) = 1.5U eq (C methyl ). The methyl groups were allowed to rotate but not to tip.
