Abstract
PURPOSE: To prepare the titled compound, directly, in high yield, by a specific treatment of the ea-type or ae-type isomer of mono-substituted cyclohexane-1- carboxylic acid ester.
CONSTITUTION: The titled compound of formula (6), e.g. trans-4-aminomethyl- cyclo-hexanecarboxylic acid methyl ester, is prepared by heating the ea-type or the ae-type isomer of a mono-substituted cyclohexane-1-carboxylic acid ester of formula (1) or formula (2) in the presence of hydrogen and a hydrogenation catalyst (e.g. a metallic catalyst such as Ru, Rh, Pd, Pt, Fe, Co, Ni, Cu, etc.) at 200W400°C, and reacting according to the mechanism shown in the reaction formula. The titled compound can be obtained directly, in high yield, by hydrogenating a mono-substituted benzene-1-carboxylic acid ester, and successively carrying out the treatment of the invention.
