(https://www.thevespiary.org/rhodium/Rhodium/chemistry/redamin.aqueous.nabh4.html), the yield won't increase beyond what is achieved from letting the imine form for ~2h, at least not when water is present.the question is rather why you want to do it. The resulting amine is rather inactive.
Are you sure this amine is inactive? I remember shulgin said something about the MDA analogue with the amine moved to the carbon next to the phenyl ring was atleast somewhat active.
And I believe in an old post you made about the book designer drugs directory, the book claimed that alpha-phenethylamine was active. This amine is just another methyl group on that compound.
