Abstract

In the title compound, C19H23NO6, the 1,4-dihydro­pyridine ring is twisted slightly from planarity, with a maximum deviation of 0.101 (1) Å, and adopts a very flattened boat conformation. The dihedral angle formed between the plane through the four C atoms of the 1,4-dihydro­pyridine ring and the benzene ring is 84.67 (7)°. In the crystal structure, inter­molecular N—H⋯O and C—H⋯O hydrogen bonds link the mol­ecules into a three-dimensional network.
