Reaction Steps

To a solution of 2-(4-benzyloxy-2-methoxyphenyl)-4-methyl-5-(3-pyridyl)imidazole (1.18 g) in methanol (12 ml) and tetrahydrofuran (6 ml) was added 10% palladium on carbon (wet ca. 50%, 0.30 g), and the mixture was stirred for 7 hours at ambient temperature under atmospheric pressure of hydrogen gas. The mixture was filtered, and the filtrate was evaporated. The residue was dissolved in methanol (20 ml), and hydrogenated again on palladium on carbon (wet, 0.50 g) for 5 hours. After the filtration, the filtrate was evaporated, and the residue was triturated in a mixture of diisopropyl ether and isopropanol (1:1 V/V) to give 2-(4-hydroxy-2-methoxyphenyl)-4-methyl-5-(3-pyridyl)imidazole (0.25 g).
