The present invention herein provides a process for production of a bicyclo[2.2.2]octylamine derivative which may be used as an intermediate for preparation of medical and pharmaceutical products. The process is quite efficient and can produce the derivative in a large-scale while using mild reaction conditions.
The process for producing a bicyclo[2.2.2]octylamine derivative comprises the steps of subjecting, to ring-formation, a compound represented by the following general formula (1):
[wherein R
1
represents an alkyl group having 1 to 6 carbon atoms, which may have a substituent; an arylmethyl group which may have a substituent; or an arylethyl group which may have a substituent], and a compound represented by the following general formula (2):
R
2
—NH
2
(2)
[wherein R
2
represents an alkyl group having 1 to 6 carbon atoms, which may have a substituent; an aralkyl group which may have a substituent; a hydroxyl group; an alkyloxy group having 1 to 6 carbon atoms, which may have a substituent; or an aralkyloxy group which may have a substituent], and then reducing the resulting product.
