MP-NEt3BH4 in place of NaBH4 for reductions

[Flip]

Is there any reason that one could not use macroporous triethylammonium methylpolystyrene borohydride in place of NaBH₄ for reductive amination?

I'm sure the DEA would rather skip it than waste an entire breath asking me why the fuck I would order macroporous triethylammonium methylpolystyrene borohydride

This product should work fine for the reduction of methylimines. The only negative is that it is bulky - about 300 grams per mole of BH₄.

Thanks,
I suspected as much but I am never 100% with anything for lack of an official education.  Been dreaming on reductions and borohydride substitutes came to mind.  I know this one is a little obscure.  I'm learning though.  I'm not sure how much this shit costs but even an inconvienient substitute is a good one, and sometimes a good precaution, when your own name is on the order form.
