(E)-2-Amino-4-(3,3-dimethyl-2-oxobutyl-idene)-1-[2-(2-hy-droxy-eth-oxy)eth-yl]-6-methyl-1,4-dihydro-pyridine-3-carbo-nitrile.

In the title compound, C(17)H(25)N(3)O(3), there are intra-molecular hydrogen bonds between an amine H atom and the ep-oxy O atom, and between a dihydro-pyridine ring H atom and the ketone O atom. In the crystal, mol-ecules are linked into a zigzag chain running parallel to the c axis by hydrogen bonds between the hy-droxy group and the ketone O atom. There are also weak C-H⋯O and C-H⋯π inter-actions which link the mol-ecules into sheets lying in the bc plane.
