Hydrazine hydrate (55% solution, 14.5 mL) was added rapidly to a suspension of (12.0 g; 64.9 mmol) of 6-Methylthio-5-nitroso-pyrimidine-2,4-diamine 2 in DMF at room temperature. The mixture was allowed to stir overnight and then the bright pink mixture was filtered and the solid washed several times with DMF followed by ether and then air dried to give 9.53 g of 6-Hydrazino-5-nitroso-pyrimidine-2,4-diamine as bright pink solid.
