Zahn, Helmut published the artcileA derivative of O-(2,4-dinitrophenyl)-DL-serine, Computed Properties of 971-66-4, the publication is Biochemische Zeitschrift (1955), 209-12, database is CAplus.

The N content of carefully purified cotton after exhaustive treatment with 2,4-(O2N)2C6H3F (Ia) (cf. C.A. 46, 7144i) increases from 0.09 to 0.22% indicating that the hydroxyl in serine has not reacted. α-N-Benzoylamino-β-hydroxyethyl propionate (I) (1.5 g.) and 1.1 g. Ia in 30 ml. dry C6H6, refluxed 6 hrs., evaporated in vacuo, and the residue treated with 15 ml. 2N HCl gave 5% EtCO2CH(NHBz)CH2OC6H3(NO2)2-2,4 (II), m. 122° (from EtOH). I (0.7 g.) was treated with 1.5 g. PhN:NC6H4COCl-p in 30 ml. C5H5N, and after 2 days H2O added and the mass evaporated in vacuo. The residue dissolved in 50 ml. CHCl3, extracted with aqueous KHSO4, and chromatographed on Al2O3 yielded EtCO2CH(NHBz)CH2O2CC6H4N:NPh-p, m. 154°.
