実験手順

A reactor was charged with 10 g (0.02 mole) of 11,15-dihydroxy-13-sulfoethyl-9,13,17-triazapentacosane, 50 ml of toluene and 5.1 ml (0.05 mole) of ethyl glycolate, and the contents were heated to 100° C. and continuously stirred for 7.5 hours while purging ethanol formed with a nitrogen stream. After completion of a reaction, the solvent was distilled off under reduced pressure, and the residue was purified by column chromatography (on 200 g of silica gel, developing solvent: chloroform/methanol=100/1→20/1), thereby obtaining 10.6 g (isolation yield: 91%) of 3,11-dioctyl-2,12-dioxo-7-sulfoethyl-3,7,11-triaza-1, 5,9,13-tridecanetetraol.
