Reaction Steps
Ac-Phe-Gly-Ala-LeuCH2Cl was prepared by condensation of N-acetyl-L-phenylalanylglycyl-L-alanine with leucine chloromethyl ketone hydrochloride using a mixed anhydride procedure employing isobutyl chloroformate. Powers et al., Biochem. Biophys. Acta. 480:246-261 (1977), describe an analogous procedure. Crude product was recrystallized from ethyl acetate to provide a white crystalline solid, m.p. 152.4°-153.8° (reported m.p. 167°-168°).
