4 ml of a 5M cyanogen bromide solution in acetonitrile were added dropwise to the solution of 3.6 g of 2-nitrobenzoic hydrazide in 20 ml of acetonitrile. This resulted first in a clear solution, then a solid precipitated out which was filtered off with suction after continuing to stir for a short time, washed again with acetonitrile and dried under reduced pressure.
