Crystal structure of cis-1-(2-methyl-1,2,3,4-tetra­hydro­quinolin-4-yl)azepan-2-one

In the title compound, C₁₆H₂₂N₂O, the azepan-2-one ring adopts a chair conformation, while the 1,2,3,4-tetra­hydro­pyridine ring adopts a half-chair conformation. In the crystal, mol­ecules are linked by N—H...O hydrogen bonds, forming supra­molecular chains propagated along [10-1], with weak C—H...O inter­actions occurring between the chains.
