METHOD OF PRODUCING 1-FORMAMIDO-3,5-DIMETHYLADAMANTANE Russian patent published in 2012 - IPC C07C231/08 C07C233/03 C07C211/38 C07C233/14 C07C237/24 C07C229/50

Abstract RU 2455281 C2

FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing 1-amino-3,5-dimethyladamantane, involving reaction of 1,3-dimethyladamantane with formamide in concentrated acids to obtain 1-formamido-3,5-dimethyladamantane, provided that neither SO₃-containing sulphuric acid nor 100% nitric acid is used, wherein the concentrated acids are 30-70% nitric acid and 90-100% sulphuric acid and further conversion of 1-formamido-3,5-dimethyladamantane to 1-amino-3,5-dimethyladamantane through hydrolysis with aqueous hydrochloric acid.

EFFECT: high efficiency of the method.
