Abstract
PURPOSE: To obtain peptide having guanido group, by forming a peptide from a starting compound wherein the guanido group is protected by mesitylene-2-sulfonyl group, and by eliminating the protecting group with a methanesulfonic acid, etc.
CONSTITUTION: One equivalent of a starting compound having a guanido group is reacted with 1W2 equivalents of a mesitylene-2-sulfonyl halogenide in the presence of a base to protect the guanido group with the mesitylene-2-sulfonyl group, and changed into a peptide. The protecting group is then eliminated by methanesulfonic or trifluoro-methanesulfonic acid in the presence of anisole to suppress side reactions due to cations formed. The desired guanido group-containing peptide is thus obtained.
EFFECT: Neither impurity formation due to the side reactions nor necessity of special vessels in eliminating the protecting group.
