Procedure
A solution of 4 g of 3-(tert.-butyl-N-cyclohexyl-amino)sydnonimine hydrochloride in 30 ml of concentrated ethanolic hydrochloric acid is left to stand at room temperature for one day and then concentrated in a rotary evaporator. The residue is purified by column chromatography (silica gel, CH2Cl2 :MeOH=9:1) and the residue obtained after concentration of the corresponding fractions is stirred with isopropyl acetate and filtered off with suction. Yield: 2.5 g melting point: 90° C. (decomp.)
