To a solution of 0.3 g (0.013 mole) of Na in 65 ml of abs EtOH was added 2.93 g (0.039 mole) of nitroethane dropwise. To the white suspension was added 2.19 g (0.01 mole) of 5-nitrogramine suspended in 40 ml of abs EtOH, followed by 2.5 g (0.02 mole) of dimethylsulfate in 20 ml of abs EtOH dropwise over 15 minutes. The mixture was stirred for 2 hours, then poured into 350 ml of ice water. The yellow solid was filtered, washed with ice water and air-dried to give 1.63 g (64%) of product: m.p. 130-131.5.
