An object of the present invention is to provide a method for producing a peptide with high efficiency.
Provided is a method for producing a peptide which comprises the following step (1):
(1) a step of reacting a peptide in which a C-terminal carboxy group is activated which is obtained by reacting an N-protected peptide represented by the formula (I):
a tertiary amine represented by the formula (II):
and an acid halide in a flow reactor,
with a silylated amino acid or peptide obtained by reacting an amino acid or peptide represented by the formula (III):
with a silylating agent,
in a flow reactor
[in the formulae (I) to (III), AA1, AA2, P, R1, R2 and R3 are as defined in the present specification and the claims].
本发明的目的是提供一种高效生产多肽的方法。
