Versuchsvorschrift

85 ml of 30% strength hydrogen peroxide solution are added to a solution of 5-amino-1-cyclopentyl-1H-pyrazole-4-carbonitrile (6.74 g, 38.3 mmol) in a mixture of 300 ml of ethanol and 371 ml of concentrated aqueous ammonia solution at room temperature and stirred at room temperature overnight. The nonaqueous solvents are then stripped off in a rotary evaporator. The product precipitates as solid from the remaining mixture and is filtered off with suction, washed with diethyl ether and dried under high vacuum.
