Reaction Steps

A solution of 16.7 g. (0.1 mol) diethyl aminomethylphosphonate in 200 ml. absolute ethanol is treated with 11.2 g. (0.1 mol) thien-2-aldehyde and the resulting mixture is heated under reflux and then evaporated to give 26 g. diethyl N-thien-2-ylidene-aminomethylphosphonate (yield: about 100%) in the form of a yellow oil giving a single spot in TLC (silica plate; eluant: ethyl acetate).
