実験手順

The title compound was synthesized via General Method 9 using 209 mg (0.6 mmol) of 4-hydroxy-6,6-bis-[2-(4-hydroxy-phenyl)-ethyl]-5,6-dihydro-pyran-2-one (prepared in Example PP), 250 mg (0.6 mmol) of [5-tert-butyl-2-methyl-4-(toluene-4-sulfonylsulfanyl)-phenoxy]-acetic acid (prepared in Example NNNN), 327 mg (2.4 mmol) of K2CO3, and DMF (2 mL). The reaction was conducted in EtOH to effect ester exchange. The reaction was worked up as described. The residue was chromatographed on silica gel eluting with (1:1 CH2Cl2 :EtOAc+2% MeOH) to yield the product, m.p. 162°-163° C. 1H NMR (DMSO-d6) δ 1.21 (t, 3 H), 1.47 (s, 9 H), 1.8 (s, 3 H), 2.0 (m, 4 H), 2.6 (m, 6 H), 2.95 (s, 2 H), 4.25 (q, 2 H), 4.75 (s, 2 H), 6.65 (m, 5 H), 6.75 (s, 1 H), 7.0 (d 4 H), 9.18 (s, 2 H).
