Ethyl 5‐amino‐1‐(4‐chloro­phenyl‐5,5‐dimethyl‐2‐oxo‐1,3,2‐dioxaphosphinan‐2‐yl)‐3‐(6‐chloro‐3‐pyridylmethyl­amino)‐1H‐pyrazole‐4‐carboxyl­ate

In the title compound, C23H26Cl2N5O5P, the P atom adopts a distorted tetra­hedral coordination. The terminal ethyl carboxyl­ate group is almost coplanar with the plane of the pyrazole ring. Intra­molecular N—H⋯O hydrogen bonds influence the overall conformation of the mol­ecule. C—H⋯π Inter­actions contribute to the crystal packing.
