Diethyl 2,6-dimethyl-4-(naphthalen-1-yl)-1,4-di­hydro­pyridine-3,5-di­carboxyl­ate

In the title compound, C23H25NO4, the 1,4-di­hydro­pyridine ring adopts a flattened boat conformation. The naphthalene ring system forms a dihedral angle of 88.59 (6)° with the pyridine ring. In the crystal, N—H⋯O and C—H⋯O hydrogen bonds generate an R12(6) ring motif and result in a zigzag chain along the b axis. Additional C—H⋯O hydrogen bonds form infinite chains along the c-axis direction.
