title: 3-Ethyl 5-methyl 2-hydr-oxy-6-methyl-4-(4-nitro-phen-yl)-2-trifluoro-methyl-1,2,3,4-tetra-hydro-pyridine-3,5-dicarboxyl-ate.
abstract: In the title compound, C(18)H(19)F(3)N(2)O(7), the tetrahydropyridine ring adopts a half-chair conformation. The nitro group is disordered over two sites with occupancies of 0.780 (15) and 0.220 (15). An intra-molecular N-H⋯F hydrogen bond is observed in the mol-ecular structure. The mol-ecules are linked into a two-dimensional network parallel to (100) by O-H⋯O, N-H⋯O and C-H⋯O hydrogen bonds.
