A mixture of 6-bromo-2-(2-ethylsulfanylphenyl)-3-methyl-3H-imidazo[4,5-b]pyridine (0.20 g), sodium periodate (0.18 g), methanol (3 ml), water (1 ml), and THF (0.4 ml) was stirred at room temperature for 3.5 hours. Water was poured thereinto under ice-cooling, and then the precipitated solid was collected by filtration. The obtained solid was washed with water and hexane, and dried to give 0.19 g of 6-bromo-2-(2-ethylsulfinylphenyl)-3-methyl-3H-imidazo[4,5-b]pyridine (hereinafter referred to as Present Compound 43).
