Diethyl 4-[2-(4-meth-oxyphenyl)-1H-pyrazol-3yl]-2,6-dimethyl-1,4-dihydro- pyridine-3,5-dicarboxylate

Abstract

In the title compound, C23H27N3O 5, the pyrazole ring is inclined at dihedral angles of 38.16 (6) and 80.80 (6) , respectively, to the least-squares planes of the benzene and dihydro-pyridine rings. In the crystal, adjacent molecules are linked via a pair of N-H?N hydrogen bonds, forming an inversion dimer. The dimers are stacked in a column along the a axis through N-H?O hydrogen bonds. Intra- and intermolecular C-H?N and C-H?O hydrogen bonds are also observed.
