Reaction Steps

Sodium hydride (60% in oil, 368 mg) was added under a nitrogen atmosphere to a solution of ethyl Z-2-(4-bromophenyl)-2-hydroxyiminoacetate (2.50 g) and 4-(4-chloromethylphenoxymethyl)-5-methyl-2-phenyloxazole (3.03 g) in N,N-dimethylformamide (25 ml) at room temperature and the mixture was stirred for 1 hour. After adding 1N HCl (12 ml), aqueous sodium bicarbonate was added, and then the mixture was extracted with ethyl acetate. The ethyl acetate layer was washed with saturated aqueous sodium chloride, dried (MgSO4) and then concentrated. The residue was subjected to column chromatography on silica gel to obtain ethyl Z-2-(4-bromophenyl)-2-[4-(5-methyl-2-phenyl-4-oxazolylmethoxy)benzyloxyimino]acetate (3.12 g, yield 61%) as a colorless oil from a fraction eluted with ethyl acetate-hexane (1:3, v/v).
