1. 2-Bis-(benzylamino)-ethane has been prepared in good yield by the reduction of the (condensation product of ethanediamine with two molecules of benzaldehyde. It was therefore tried to condense ethanediamine with one molecule of benzaldehyde and to reduce the compound so obtained to the corresponding mono-benzyl derivative. 1. I- Benzylidene-amino-2-arninoethane C, H,. CH: N. CH,. CH,. NH,. Even when ...
