In the title compound, C19H17N2O3P, the six-membered 1,3,2-oxazaphosphorine ring adopts a twist-boat conformation with the phosphoryl O atom in an equatorial position. The P=O(oxide) bond length is 1.457 (1) Å and the average value of the P—O distances is 1.588 Å. The crystal structure is stabilized by C—H...O and C—H...π interactions.
