Aniline → HCID 20541269, compound

Participants

Reaction Steps

10.3 g (0.05 mol) of 2-chloro-3a,4,5,6-tetrahydroperimidine are introduced into 15 ml of aniline, whilst stirring. After the strongly exothermic reaction has subsided (temperature rises to 90° C.), water is added to the mixture and the crystals which have precipitated are isolated by filtration and washed several times with dilute aqueous ammonia solution. 2-Phenylamino-3a,4,5,6-tetrahydro-perimidine is obtained. Yield: 9.5 g (72% of theory) of melting point 233°-235° C.
