The present invention provides methods for producing peptide compounds. The inventors have found that a cyclic peptide compound can be produced efficiently by linking the N-terminal amino acid residue and the C-terminal amino acid residue of a peptide compound in a solvent containing one or more selected from the group consisting of water-immiscible solvents, water-soluble alkyl nitriles, and water-soluble ethers.

The interaction of 1,3-dialkyl-2,3-dihydro-1H-benzo[d]imidazol-2-ylidenemethyl cyanides with N-trifluoroacylated acid chlorides gave the desired (3-cyano-2-oxo-3-hetarylpropyl)-2,2,2-trifluoroacetamides that upon detrifluoroacetylation provided the target 2-(5-amino-2,3-dihydro-3-oxopyrrol-4-yl)-1,3-dialkylbenzimidazolium chlorides.[GRAPHICS]
