Procedure

The title compound was prepared as described in General Method 9 from 6-cyclohexyl-4-hydroxy-6-[2-(4-hydroxy-phenyl)-ethyl]-5,6-dihydro-pyran-2-one (prepared in Example NN; 156 mg, 0.499 mmol), toluene-4-thiosulfonic acid S-(2-tert-butyl-4-hydroxymethyl-5-methyl-phenyl) ester (prepared in Example FFF; 250 mg, 0.546 mmol), K2CO3 (303 mg, 2.195 mmol), and DMF (4 mL). The reaction was stirred at room temperature for 2.5 hours and then worked up in the usual manner. The crude product was flash chromatographed using CH2Cl2 : MeOH (98:2) to give the desired product as a solid, m.p. 138°-139° C. (dec.). 1H NMR (CDCl3) δ 1.0-2.1 (m, 13 H), 1.58 (s, 9 H), 2.03 (s, 3 H), 2.6-2.7 (m, 3 H), 3.05 (d, 1 H), 4.6 (s, 2 H), 6.69-6.74 (d, s, 3 H), 6.98 (d, 2 H), 7.34 (s, 1 H), 7.74 (s, 1 H).
