Reaction Conditions

Reaction Steps

A mixture of 1.15 g of 3-ethylsulfanylpyrazine-2-carboxylic acid (2-methylamino-5-trifluoromethylpyridin-3-yl)-amide, 1.23 g of p-toluenesolufonic acid-hydrate and 5 ml of NMP 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 mixture was extracted with ethyl acetate. The organic layer was washed with water, then dried over anhydrous magnesium sulfate and concentrated under reduced pressure. The resulting residue was applied to a silica gel column chromatography to obtain 631 mg of 2-(3-ethylsulfanylpyrazin-2-yl)-3-methyl-6-trifluoromethyl-3H-imidazo[4,5-b]pyridine (hereinafter, referred to as Compound of Present Invention 6).
