Reaction Steps
Thin layer chromatography on silica gel plates (Merck) with butanol:acetic acid:water (4:1:1) indicated a single spot, Rf 0.37, by uv and by ninhydrin and Sakaguchi stains. Amino acid analysis of the D-Phe-Pro-ArgCH2Cl. 2HCl following hydrolysis in 2 ml of 6.0 N HCl for 24 hr. at 110° C. gave Phe=0.98 and Pro=1.00.
