Procedure
Heat a solution of 3-[[4-(4-acetyl-3-hydroxy-2-methyl-phenoxymethyl)-phenyl]-(tetrahydro-pyran-2-yloxy)-methyl]-benzoic acid thiosemicarbazide (1.20 g, 2.04 mmol) and potassium hydroxide (0.228 g, 4.08 mmol) in acetone (5.0 mL) and water (5.0 mL) overnight. Acidify with 2N hydrochloric acid and extract with ethyl acetate (5×). Combine organic layers and wash with brine, dry, and concentrate to afford the title compound which was used without further purification (1.12 g, 2.04 mmol, 99%). MS (m/z): 544 (M−H).
