Reaction Steps

A mixture of 2-amino-5-iodobenzoic acid (5.20 g, 19.8 mmol), 1,1,1-trifluoro-3-phenylpropan-2-one (3.95 g, 21.0 mmol), and Eaton's reagent (12 mL) in a sealed tube was heated at 100° C. for 2 hours. More 1,1,1-trifluoro-3-phenylpropan-2-one (1.60 g, 8.50 mmol) was added and the mixture was heated for another 2 hours. The reaction was then cooled to room temperature, ice water was added, and the mixture was stirred vigorously for about 20 minutes. 50% Aqueous NaOH and concentrated NH4OH solutions were added until pH 9. The resulting dark brown gummy material that formed was diluted with DCM which resulted in a solid precipitate that was collected by filtration. The solids were washed with water and Et2O and air dried to provide the title compound.
