Reaction Steps

A mixture of 0.40 g of 5-tert-butyl-2-(2-chloro-5-trifluoromethylpyridin-4-yl)benzoxazole, 0.59 g of 5% palladium on carbon and 25 ml of acetic acid was stirred under about one atmosphere of hydrogen at room temperature for 15 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 0.19 g of 5-tert-butyl-2-(3-trifluoromethylpyridin-4-yl)benzoxazole (hereinafter, referred to as “active compound 107”).
