Reaction Steps

To a solution of 4-[4-[2-(2-hydroxyethyl)-1H-imidazol-1-yl ]butyl]phenol (260 mg) in DMF (4 ml), 60% oily sodium hydride (44 mg) was added under ice cooling. After stirring at room temperature for 30 minutes, (E)-4-chloromethyl-2-[2-(2,4-difluorophenyl) ethenyl]oxazole (281 mg) was added under ice cooling. After stirring at room temperature for 3 days, water was added under ice cooling. The precipitate was collected by filtration and washed with water. The precipitate was dissolved in a mixture of ethyl acetate-THF and dried over magnesium sulfate, after which it was concentrated under reduced pressure. The residue was recrystallized from ethyl acetate-hexane to yield the titled compound (275 mg) as pale-yellow crystals.
