Reaction Steps

7.5 g of 5-nitro-1H-pyrazole-3-carboxylic acid were dissolved in 70 ml of DMF. 19.9 g of HATU and 9.6 g of triethylamine are added at RT and, after stirring for 10 minutes, 5.1 g of aminomethylcyclopropane hydrochloride are added, and the mixture is stirred at RT overnight. After aqueous workup, the crude product is purified by column chromatography (silica gel, methanol:DCM=1:30).
