Participants

Reaction Steps

To a slurry of 2-methyl-4[4,5-dichloro-2-nitroanilino]-1,2,3-triazole-5-carbonitrile (1.1 g) in ethanol (10 ml) was added anhydrous stannous chloride (2.0 g) in concentrated hydrochloric acid (10 ml) and the solution heated at reflux for one hour, cooled and the resulting solid filtered and dried at 70° C. under reduced pressure to give an orange crystalline solid, recrystallised from ethanol, melting point >255° C.
