Abstract
Impure 5-aminohexahydropyrimidines containing traces of nickel are purified by adding thereto sufficient ammonia to convert the nickel to a nickel-ammonia complex, which is then separated. An example relates to the purification of 5-amino - 5 - methyl - 1, 3 - bis (2 - ethylhexyl) - hexahydropyrimidine.
