Procedure

An EtOH (12.5 ml) solution containing mucobromic acid (12.9 g) was added dropwise to a solution comprising sodium nitrate (13.1 g) and water (12.5 ml) at 50° C., followed by stirring for 0.5 hours. The reaction solution was adjusted to room temperature, a solid precipitate was collected by filtration. The obtained residue was washed with EtOH. A yellow solid of sodium (1,3-dioxopropan-2-ylidene)azinate (3.82 g) was thus obtained.
