  I believe that the large excess of NaBH4 is because they keep trying to do it on a substrate without any liquid, ie: dry conditions... it would probablly work better on a substrate in a liquid suspension...

It is available in PDF from the homepage of J. Chin. Chem. Soc. too.

it would probablly work better on a substrate in a liquid suspension...
And it would probably work even better in methanol at room temperature.

Thx! I couldn't get that stupid quicktime plugin to give me more that one page...

doing similar reactions (reductive aminations of ketones) using this system on clay, or zeolit supports in a microwave.
Anyway the chemist would place a bowl filled with dry ice/alcohol slush on top of the beaker while the mix was being microwaves when dealing more volitile amines to recondense them.
