A mixture of 7.2 g (0.0227 mole) of 2,4,6-trinitro-1,3,5-trichlorobenzene and 70 ml of methanol was stirred in an ice bath while a solution of 9.9 g (0.162 mole) of ethanolamine in 70 ml of methanol was added over 10 min. Stirring at room temperature gave a solution from which yellow solid precipitated until the mixture became too thick to stir. After standing for 2 hr., the mixture was filtered to give 7.6 g (86%) of 2,4,6-trinitro-1,3,5-tris(2-hydroxyethylamino)benzene; 1H NMR (DMSO-d6): 3.48 (m, 6H), 3.72 (m, 6H).
