Procedure

A mixture of dibutyl aminomethylphosphonate (69.7 g) and benzaldehyde (33.0 g) in benzene (600 ml) is stirred with magnesium sulfate (150 g) for 3 hours. The mixture is filtered and the salts washed with benzene. Concentration of the filtrate in vacuo leaves dibutyl N-benzylideneaminomethylphosphonate.

Workup

  1. filtrationThe mixture is filtered
  2. washthe salts washed with benzene
