Procedure

Add p-toluenesulfonic acid (16.8 mg, 0.098 mmol) to a solution of 3-[[4-(4-acetyl-2-chloro-3-hydroxy-phenoxymethyl)-phenyl]-(tetrahydro-pyran-2-yloxy)-methyl]-benzoic acid (1.00 g, 1.96 mmol) in methanol (0.20M) and stir overnight. Evaporate solvents, dilute with ethyl acetate and wash with water (1×) and brine (1×). Dry and concentrate to afford the title compound as a white solid (0.786 mg, 1.84 mmol, 94%): MS (m/z): 426 (M−H).
