DMTMM-mediated amidation of HA proceeds through an aromatic substitution forming an intermediate s-triazine ester of HA reactive towards amines (compound 1, Scheme 1). Use of DMTMM for bioconjugations has been reported at both alkaline (Pelet & Putnam, 2011) and acidic pH (Nimmo et al., 2011, Yu et al., 2014).

For all the substrates tested DMTMM yields were superior at parity of feed ratio.
