1. A method for producing a peptide compound, comprising:
a step of using an aromatic heterocyclic compound represented by Formula (1),
![]() in Formula (1),
a ring A represents an aromatic heterocyclic ring,
YA represents —OH, —NHR, SH, or —X0, where R represents a hydrogen atom, an alkyl group, an aromatic group-substituted alkyl group, a heteroaromatic group-substituted alkyl group, or a 9-fluorenylmethoxycarbonyl group, and X0 represents Cl, Br, or I,
RA's each independently represent an aliphatic hydrocarbon group or an organic group having an aliphatic hydrocarbon group, and the ring A may further have a substituent in addition to RA,
RB's each independently represent a monovalent aliphatic hydrocarbon, a (1+c)-valent aromatic group, or a (1+c)-valent heteroaromatic group,
RC's each independently represent an aliphatic hydrocarbon group or an organic group having an aliphatic hydrocarbon group,
m represents an integer of 0 to 2, a represents an integer of 0 to 5, and c represents an integer of 0 to 5,
in a case where both a and c are 0, RB is a monovalent aliphatic hydrocarbon group, and
the number of carbon atoms in at least one aliphatic hydrocarbon group of RA, RB, or RC is 12 or more.
