Versuchsvorschrift
0.3 g 3-Cyano-2-morpholino-5,4'-bipyridine-1'-oxide is dissolved in acetone with heating. The solution is allowed to cool, then treated with 0.1 ml methanesulfonic acid and concentrated under vacuum in the rotary evaporator. The oily residue is dissolved in acetone. The resulting solution is mixed with ether until crystallization, then is cooled and filtered with suction. The material filtered out is washed with acetone and ether and dried. Yield: 0.3 g (74.0% of the theoretical yield), the melting point is 151° C.-154° C.
