Reaction Steps

A solution of 2-fluoro-4-iodoaniline (15 g, 63.29 mmol) and diethyl ethoxymethylene malonate (41.05 g, 0.19 mol) in toluene (75 mL) was heated to reflux with a Dean-Stark condenser for 7 h. The mixture was cooled, concentrated and washed with methyl tert-butyl ether (500 ml). The methyl tert-butyl ether layer was then concentrated and the residue was washed with heptane (500 ml), yielding a white solid that precipitated out of the yellow solution. This solid was then collected, yielding 23.6 g (91%) of diethyl 2-((2-fluoro-4-iodophenylamino)methylene)malonate.
