Participants

Reaction Steps

A mixture of methyl 4-[4-[2-(2-furyl)-5-methyl-4-oxazolylmethoxy]phenyl]acetoxy-5-oxo-5-phenylpentanoate (1.49 g), ammonium acetate (777 mg) and acetic acid (5 ml) was refluxed for 3 hrs. After cooling, ethyl acetate was added to the reaction mixture. The obtained ethyl acetate solution was washed with saturated aqueous sodium hydrogen carbonate and then saturated brine, dried (MgSO4) and concentrated. The residue was subjected to silica gel column chromatography, and methyl 3-[2-[4-[2-(2-furyl)-5-methyl-4-oxazolylmethoxy]benzyl]-4-phenyl-5-oxazolyl]propionate (1.11 g, yield 77%) was obtained as a colorless oil from a fraction eluted with ethyl acetate-hexane (2:3, volume ratio).
