Participants

Reaction Steps

3-methyl-2-butenylamine (3.0 g) is added dropwise at room temperature to a slurry of 1-methyl-3-nitro-1 -nitrosoguanidine (4.3 g) in 50 ml of EtOH/H2O (1/1). After stirring the mixture at room temperature for 18 hours, the precipitate which forms is removed by filtration. The solid is then slurred with dilute hydrochloric acid, collected by filtration and washed with ethanol/water (30/70). Recrystallization from ethanol gives a white solid with mp 134°-136° C.
