Abstract: 2-Nitro-1,3-bis (3,3'-dihydroxymethyl)-1,2,3-triazolyl-2-azapropane (2-NDTAP) is of interest as a starting material in the
synthesis of high-energy compounds. The article discusses the synthesis of 2-NDTAP the reaction of azide-alkyne cycloaddition
1,3-diazido-2-nitro-2-azapropane with propargyl alcohol in tert-butyl alcohol in the presence of a copper catalyst (wire, copper
powder, copper oxide, nano copper oxide). The influence of the catalyst and the temperature of the process on its duration, yield and
product quality has been investigated. The structure of 2-NDTAP was confirmed by IR and NMR spectroscopy. As a result, a method
for obtaining 2-NDTAP with a yield of 62 % and a basic substance content of more than 97 % was developed.
