Reaction Steps

A solution 1.0 mmol of diethyl 2-thiophenephosphonate in tetrahydrofuran was treated with 1.12 mmol LDA at −78° C. for 20 min. 1.5 mmol methyl formate was added and the reaction was stirred for 1 hr. Extraction and chromotagraphy gave 5-diethylphosphono-2-thiophenecarboxaldehyde as a clear yellow oil.
