(E)-2-Amino-4-(3,3-dimethyl-2-oxobutyl­idene)-1-[2-(2-hy­droxy­eth­oxy)eth­yl]-6-methyl-1,4-dihydro­pyridine-3-carbo­nitrile

In the title compound, C₁₇H₂₅N₃O₃, there are intra­molecular hydrogen bonds between an amine H atom and the ep­oxy O atom, and between a dihydro­pyridine ring H atom and the ketone O atom. In the crystal, mol­ecules are linked into a zigzag chain running parallel to the c axis by hydrogen bonds between the hy­droxy group and the ketone O atom. There are also weak C—H...O and C—H...π inter­actions which link the mol­ecules into sheets lying in the bc plane.
