4-(4,6-Dimethoxy[1,3,5]triazin-2-yl)-4-methyl-morpholinium Chloride (DMTMM): A Valuable Alternative to PyBOP for Solid Phase Peptide Synthesis

The salt formed from 2-chloro-4,6-dimethoxy[1,3,5]triazine and N-methylmorpholine (DMTMM) is an effective coupling agent for solid phase peptide synthesis that can be used as economical alternative to PyBOP. Several oligopeptides were prepared on a Wang type resin using this reagent and the yields and purity of the products were always comparable with those obtained with PyBOP as the coupling agent.
