2-(benzylideneamino)-N,N-dimethylethanamine

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A solution of 88.0 g of N,N-dimethylethylenediamine in 150 ml. of benzene is treated with a solution of 106 g of freshly distilled benzaldehyde in 150 ml. of benzene. This mixture is stirred and refluxed for 2 hours while collecting 22 ml. of an aqueous layer in a Dean-Stark tube. The solvent is then distilled and the residue fractionated to give 156 g of distillate, boiling point 98°-100° C. at 4 mm. of Hg. refluxed for 2 hours while collecting 22 ml The solvent is then distilled the residue fractionated to give 156 g of distillate, boiling point 98°-100° C. at 4 mm. of Hg

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.
