Procedure

The title compound was prepared as described in General Method 6 from 1.50 mmol of 3-bromo-5,6-dihydro-4-hydroxy-6-phenyl-6-(2-phenylethyl)-2H-pyran-2-one (prepared in example BBB), 1.60 mmol of 2-isopropylbenzenethiol, and 1.60 mmol of piperidine in 30 mL of dichloromethane. The product was triturated with hexane:ether (1:1) to afford a solid. The crude product was chromatographed on silica gel, eluting first with chloroform and then with 5% methanol in chloroform, to give the title compound (m.p. 66°-67° C.). 1H NMR (DMSO-d6) δ 1.16 (t, 6 H), 2.21-2.35 (m, 3 H), 2.60 (m, 1 H), 3.21 (m, 1 H), 3.42 (q, 2 H), 5.88 (d, 1 H), 6.56 (t, 1 H), 6.94 (t, 1 H), 7.13 (m, 4 H), 7.25 (m, 2 H), 7.45 (m, 5 H).
