Method for producing a peptide compound, a reagent for forming a protecting group, and an aromatic heterocyclic compound

摘要

It relates to a method for producing a peptide compound comprising the step of using an aromatic heterocyclic compound represented by formula (1), a reagent for forming a protecting group containing the compound, and the compound. In formula (1), ring A represents an aromatic heterocycle, Y A each independently represents -OH, -NHR, -SH, or -X 0 , X 0 represents Cl, Br or I; R A and R C each independently represent an aliphatic hydrocarbon group or an organic group having an aliphatic hydrocarbon group, and R B are each independently a monovalent aliphatic hydrocarbon group, a (1+c) aromatic group or ( 1+c) represents a valent heteroaromatic group, and when both a and c are 0, R B is a monovalent aliphatic hydrocarbon group, and the number of carbon atoms in at least one of R A , R B and R C is 12 More than that.
