A mixture of 450 mg of 3-amino-5-trifluoromethylpyridine-2-thiol, 637 mg of 4-ethylsulfanylnicotinic acid hydrochloride, 532 mg of EDCI hydrochloride, 31 mg of HOBt and 5 ml of pyridine was stirred at room temperature for 2 hours and then stirred at 60° C. for 30 minutes. Water was poured to the reaction mixture, and the precipitated solid was filtered. The resulting solid was washed with water and n-hexane and then dried to obtain 494 mg of 4-ethylsulfanyl-N-[2-mercapto-5-(trifluoromethyl)pyridin-3-yl]nicotinamide. 4-ethylsulfanyl-N-[2-mercapto-5-(trifluoromethyl)pyridin-3-yl]nicotinamide
