It had been found that epinephrine underwent decomposition with hydrochloric acid partially forming a compound having a dibenzocycloheptatriene ring. Ephedrinetype compound possessing alkoxyl in 3- and 4-positions of benzene ring was also expected to undergo the same reaction but its acid decomposition unexpectedly afforded 3, 4-dialkoxyphenylacetone as the main product. This shows that the reaction is no different from the so-called hydramine decomposition and a sevenmembered compound was not obtained in this reaction.
