Reaction Steps

The title compound was prepared as described in General Method 6 from 2.0 mmol of 3-bromo-5,6-dihydro-4-hydroxy-6-phenyl-6-(2-phenylethyl)-2H-pyran-2-one (prepared in example BBB), 2.1 mmol of 2-sec-butylbenzenethiol, and 2.1 mmol of piperidine in 25 mL of dichloromethane. The product was chromatographed on silica gel, eluting first with chloroform and then with 5% methanol in chloroform, to give the title compound (m.p. 67°-68° C.). 1H NMR (DMSO-d6) δ0.82 (q, 3H), 1.09 (t, 3H), 1.46-1.61 (m, 2H), 2.26 (m, 2H), 2.35 (m, 1H), 2.62 (m, 1H), 2.98 (m, 1H), 3.47 (q, 2H), 5.90 (t, 1H), 6.56 (t, 1H), 6.94 (t, 1H), 7.07-7.18 (m, 4H), 7.25 (m, 2H), 7.45 (m, 5H).
