It is known that one can be produced, for example, from cyclohexene-1,3-dione (dihydroresorcinol) and ammonia by dehydration condensation (Natur Wissen).
vol. 47, p. 83 (1960)). However, the dihydroresorcin used in this method is usually produced by partial reduction of m-dihydroxybenzene (resorcin), and it has the disadvantages that resorcin is expensive and the manufacturing process is long, so it is not used industrially. I can't say it's an advantageous method.

なプロセスであると言える。 Furthermore, a method for obtaining 3-amino-2-cyclohexane-1-one by cyclization-hydrolytic decomposition of 5-oxohexanenitrile at high temperature in the presence of a basic catalyst and an organic polar solvent has been disclosed (particularly 1977-
92942)) It can be said that it is an industrially uneconomical process, as it has a low selectivity, requires high temperatures of 160°C or higher, and requires removal of the organic polar solvent to isolate the product.
