Participants

Reaction Steps

A solution of 2-(4-chlorophenoxy)-5-thiazolecarboxaldehyde from above and (carboethoxymethylene)triphenylphosphorane (9.51 g, 27.3 mmol) in toluene (125 mL) was refluxed for 1 hr. It was then cooled to r.t. and concentrated in vacuo. The residue was taken up in ether and the triphenylphosphine filtered off. The filtrate was concentrated to afford ethyl trans-3-(2-(4-chlorOphenoxy)-5-thiazolyl)propenoate which was used as is.
