Versuchsvorschrift

After a mixture of 4-(5-methyl-2-phenyl4-oxazolylmethoxy)benzyloxyamine (600 mg), 6-oxo-6-phenylhexanamide (396 mg), acetic acid (0.331 ml), sodium acetate (317 mg) and ethanol (20 ml) was heated to reflux for 18 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 to obtain crystals from an ethyl acetate-hexane (3:1, v/v)-eluted fraction. The crystals were recrystallized from ethyl acetate-hexane to obtain E-6-[4-(5-methyl-2-phenyl-4-oxazolylmethoxy)benzyloxyimino]-6-phenylhexanamide (651 mg, yield 68%) as colorless crystals. m.p. 95-96° C.
