If N-Ethyl Benzenesulfonimine is stable and doesn't polymerize
this could be a cool new way to (subst.) amphetamines.

comments please!

What advantages does this synthesis offer over the generally simpler PhCH2CN + MeMgI (or PhCH2MgCl + CH3CN) followed by NaBH4 reduction (even if the N-ethyl analog imine would work the same as the N-benzyl)?

Ph-MeX is easyer to make then MeCN / PhMeCN is to get.
You don't need NaBH₄ or any other reduction catalyst.
Maybe milder reaction conditions in comparison to Grignards.
It's just another route that may have its advantages and disadvantages.
