Dried Eucalyptus Regnans sawdust oxidized with nitrobenzene and alkali @ 150 C yielding 4% of springaldehyde.

Methylation @ 0 - 5 C for 1hr with Me2SO4, then heated at 70 for 1hr gave 56% 3,4,5 trimethoxybenzaldehyde.

Converted to the cyanohydrin ( ie + KCN + weak acid - jm ) then reduced with Pb black to mescaline. Overall yield 1% from dried sawdust.

E. obliqua and E. diversicolour both gave 0.7% yields.
