Reaction Steps

A mixture of 703 mg of 2-ethylsulfanyl-6-trifluoromethylpyridine-3-carboxylic acid (2-methylamino-5-trifluoromethylpyridin-3-yl)-amide, 630 mg of p-toluenesolufonic acid-hydrate, 2.5 ml of DMF and 0.5 ml of toluene was heated and stirred at 150° C. for 2 hours. A saturated aqueous sodium bicarbonate solution was poured to the cooled reaction mixture, and the precipitated solid was filtered. The resulting solid was washed with water and n-hexane, and then dried to obtain 616 mg of 2-(2-ethylsulfanyl-6-trifluoromethylpyridin-3-yl)-3-methyl-6-trifluoromethyl-3H-imidazo[4,5-b]pyridine (hereinafter, referred to as Compound of Present Invention 4).
