実験手順

This compound was prepared using known reactions, starting from 97% pure 4-propyl-1,2- benzenediol. This starting product, having an odor of the copper, phenolic, slightly fatty type, was converted in an analogous way to that described in U.S. Pat. No. 3,799,892 to give a crude product which, after purification and crystallization in heptane at -20° C., gave 7-propyl-2H,4H-1,5-benzodioxepin-3-one with a purity above 99%, showing the following spectral data:
