Reaction Steps

To a suspension of 10.0 g (0.065 mol) of 2-amino-4-nitrotoluene in ethanol (20 ml) was added 65% nitric acid (4.6 ml, 0.065 mol) dropwise at 0° C. and stirred for 10 minutes. Cyanamide (8.32 g, 0.198 mol) in water (5 ml) was added to the reaction mixture then was refluxed for 25 hours, cooled to 0° C. and filtered and washed with water to yield 2-methyl-5-nitrophenyl-guanidine nitrate.
