Reaction Steps

Dimethyl 2-(2-chloro-1,1,2-trifluoro-2-(1,1,2,3,3,3-hexafluoro-2-(perfluoropropoxy)propoxy)ethoxy)terephthalate as prepared in Example 3 (10.00 g, 0.0148 mol) was added to a solution of water (100 mL) and potassium hydroxide (KOH, 8.0 g) in a reaction flask. The resulting solution in the reaction flask was heated to reflux overnight, cooled to room temperature (about 25° C.) and then acidified by adding concentrated HCl to the reaction flask to achieve a pH of ˜1, determined by the formation of a precipitate in the reaction flask. The resulting precipitate was filtered and dried under vacuum. NMRs of this precipitate showed the desired material, 2-(2-chloro-1,1,2-trifluoro-2-(1,1,2,3,3,3-hexafluoro-2-(perfluoropropoxy)propoxy)ethoxy)terephthalic acid.
