Procedure

500 mg (3.20 mmoles) of 1-methyl-3-methylamino-4-nitropyrazol are hydrated in 50 ml absolute methanol with catalytic quantities of palladium/carbon at room temperature and 30 bar. The hydration is concluded after 17 hours, a pale orange precipitate is precipitated out of the filtrated solution when adding 314 mg (3.20 mmoles) of concentrated sulfuric acid, which precipitate is removed by suction and dried.
