Reaction Conditions

Reaction Steps

A solution of phosphorous pentoxide (1.17 g, 8.21 mmole) in methanesulfonic acid (14.38 g) is treated with 2-[4-(trifluoromethoxy)phenoxy]fumaric acid (2.00 g, 6.85 mmole), stirred for 16-18 hours at ambient temperatures and for 7 hours at 70° C., cooled to room temperature and poured onto ice. The resultant mixture is filtered and the filtercake is dried to afford the title product, 1.75 g, (93% yield), mp 192°-194° C., identified by 1H and 13CNMR, IR, mass spectral and elemental analyses.
