The positions of the two phenolic hydroxyl groups were determined from the reactions of di-0-ethyl-( + )-tembetarine (LXVII R = C2H5). When the ethylated base was submitted to a Hofmann reaction, it afforded a methine which on oxidation yielded 4-ethoxy-3-mcthoxy-benzoic acid (LIU). Treatment with ethanolamine gave a tertiary base (LII) which was oxidized without further purification to 7-cthoxy-6-mothoxj -2-methyl-l-oxotetrahydroisoquinolinc (LV).
