실험 절차

After a mixture of 4-(5-methyl-2-phenyl-4-oxazolylmethoxy)benzyloxyamine (1.00 g), 4-oxo-4-phenylbutanamide (571 mg), acetic acid (0.553 ml), sodium acetate (528 mg) and ethanol (20 ml) was heated to reflux for 10 hours, the mixture was cooled to room temperature. Water was added to the reaction mixture and extracted with ethyl acetate. The ethyl acetate layer was washed with an aqueous saturated solution of sodium chloride, dried (MgSO4) and concentrated. The residue was subjected to silica gel chromatography and concentrated a portion from an ethyl acetate-hexane (3:1, v/v)-eluted fraction which eluted following the E-compound, to obtain crystals. The crystals were recrystallized from ethanol to obtain Z-4-[4-(5-methyl-2-phenyl-4-oxazolylmethoxy)benzyloxyimino]-4-phenylbutanamide (120 mg, yield 8%) as colorless crystals. m.p. 110-112° C.
