Reaction Steps

To 30 cm3 of concentrated sulphuric acid were added 8.5 g (0.044 mol) of 5-acetamido-1-methyl-3-tert-butylpyrazole, at 5° C. with vigorous stirring, followed by 2.5 cm3 (0.066 mol) of fuming nitric acid. After stirring for 2 hours, the reaction mixture was poured onto 100 g of ice and stirred for 30 minutes. The solid obtained was filtered off on a sinter funnel, washed with 20 cm3 of water and then dried under vacuum at 40° C. 8.5 g of the expected product were obtained in the form of a yellow solid, the melting point of which was 124° C.
