Reaction Steps

4-(1,1,2-trifluoro-2-(1,1,2,3,3,3-hexafluoro-2-(perfluoropropoxy)propoxy)ethoxy)benzoic acid (52.00 g, 0.0912 mol) as prepared in Example 12 and thionyl chloride (365 g, 3.09 mol) were place in an oven dried RB flask equipped with a stirrer, reflux condenser and under nitrogen. The reaction was placed in an oil bath and heated to a gentle reflux overnight. The content was analyzed by proton NMR and shown to be 4-(1,1,2-trifluoro-2-(1,1,2,3,3,3-hexafluoro-2-(perfluoropropoxy)propoxy)ethoxy)benzoyl chloride.
