反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: The mole ratio of N-(hydroxymethyl)formamide to triethylphosphite in step (2) of the process of the invention is 1:1. The reaction is conducted in the presence of heat and at a temperature sufficient to cause the reaction to go to completion. The reactants are heated until ethyl alcohol starts to evolve and this occurs at reflux temperature. When triethylphosphite is used, this temperature is approximately 120°-125° C. At this point, the alcohol is distilled off, leaving the product diethyl-N-(formyl)aminomethylphosphonate as the residue. of heat and at a temperature sufficient the reaction at reflux temperature is approximately 120°-125° C At this point, the alcohol is distilled off
