3,5-Dimethyl-1H-pyrazole-1-carboxamidine mononitrate → HCID 86749010, compound

Participants

Reaction Steps

2 g of nitronium tetrafluoroborate were added little by little to a suspension of 2.01 g of 3,5-dimethyl-1H-pyrazole-1-carboxamidine nitrate in 150 ml of absolute acetonitrile, with cooling with ice in argon atmosphere, and the reaction mixture was stirred for 30 minutes with cooling with ice. The solvent was removed by distillation under reduced pressure, and the residue was washed with chloroform to obtain 2.43 g of 3,5-dimethyl-4-nitro-1H-pyrazole-1-carboxamidine nitrate.
