Reaction Steps

A mixture of 0.34 g of 2-(3-ethynylpyridin-4-yl)-5-(trifluoromethyl)benzoxazole, 0.10 g of 5% palladium on carbon and 8 ml of ethyl acetate was stirred under about one atmosphere of hydrogen at room temperature for two hours. The reaction mixture was filtered through Celite™. The filtrate was concentrated under reduced pressure. The residue was subjected to silica gel column chromatography to give 0.33 g of 2-(3-ethylpyridin-4-yl)-5-(trifluoromethyl)benzoxazole (hereinafter, referred to as “active compound 35”).
