Versuchsvorschrift

Dimethyl 5-(1,1,2-trifluoro-2-(perfluoropropoxy)ethoxy)isophthalate (47.6 g, 0.10 mol) was added to a solution of water (1.00 L) and KOH (206 g, 3.5 mol). The resulting solution was heated to reflux for about 48 hours. The reaction was cooled to room temperature and then acidified to a pH of about 1 with concentrated HCl. The precipitate material was filtered and then dried under vacuum for 4 days to give 38.51 g of product.
