Disclosed is a production process which can synthesize a bicyclo[2.2.2]octylamine derivative (which can be used as an intermediate for the production of a pharmaceutical agent) efficiently under mild conditions in a large quantity. The bicyclo[2.2.2]octylamine derivative can be produced by cyclizing a compound represented by general formula (1) [wherein R1 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] with a compound represented by general formula (2): R2-NH2 [wherein R2 represents an alkyl group having 1 to 6 carbon atoms which may have a substituent, an aralkyl group which may have a substituent, a hydroxy 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 reducing the resulting product.

L'invention porte sur un procédé de fabrication qui permet de synthétiser un dérivé de bicyclo[2.2.2]octylamine (qui peut être utilisé comme intermédiaire pour la fabrication d'un agent pharmaceutique) de façon efficace dans des conditions douces dans une grande quantité. Le dérivé de bicyclo[2.2.2]octylamine peut être obtenu par cyclisation d'un composé représenté par la formule générale (1) [dans laquelle R1 représente un groupe alkyle ayant 1 à 6 atomes de carbone qui peut avoir un substituant, un groupe arylméthyle qui peut avoir un substituant, ou un groupe aryléthyle qui peut avoir un substituant] avec un composé représenté par la formule générale (2) : R2-NH2 [dans laquelle R2 représente un groupe alkyle ayant 1 à 6 atomes de carbone qui peut avoir un substituant, un groupe aralkyle qui peut avoir un substituant, un groupe hydroxy, un groupe alkyloxy ayant 1 à 6 atomes de carbone qui peut avoir un substituant, ou un groupe aralkyloxy qui peut avoir un substituant], et réduction du produit résultant.
