Procedure

The title compound was prepared as described in General Method 6 from 2.0 mmol of 3-bromo-5,6-dihydro-4-hydroxy-6-(3-methylbutyl)-6-phenyl-2H-pyran-2-one (prepared in example CCC), 2.2 mmol of 2-isopropylbenzenethiol, and 2.2 mmol of piperidine in 30 mL of dichloromethane. 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. 64°-66° C.). 1H NMR (DMSO-d6) δ0.80 (m, 6H), 0.95 (m, 1H), 1.17 (t, 7H), 1.42 (m, 1H), 1.93 (m, 2H), 3.20 (m, 1H), 3.45 (2H+H2O), 5.84 (d, 1H), 6.55 (t, 1H), 6.93 (t, 1H), 7.12 (d, 1H), 7.40 (m, 5H).
