Procedure

A mixture of exo-2-aminonorbornane and 2-chloronicotinic acid was stirred at 160° C. for 1 day and then spontaneously cooled. The reaction liquid was diluted with 1 M sodium hydroxide aqueous solution and then washed with diethyl ether. The water layer was neutralized with 1 M hydrochloric acid and then the precipitated crystals were collected by filtration to obtain rel-2-[(1R,2R,4S)-bicyclo[2.2.1]hept-2-ylamino]nicotinic acid.
