PROCEDURE

实验过程

This compound was prepared from Z-Leu-Phe-OH and butyl oxalyl chloride in 43% yield by the procedure described for the synthesis of Z-Leu-Phe-CO2Et, except that butyl oxalyl chloride was used in place of ethyl oxalyl chloride and sodium butyloxide in butanol was used for enol ester hydrolysis. Single spot on TLC, Rf =0.54 (CHCl3 :CH3OH=50:1) MS(FAB) m/e=497 (m+1), 1H NMR (CDCl3) ok.
