Reaction Steps

The title compound was prepared as described in General Method 6 from 1.0 mmol of 3-bromo-5,6-dihydro-4-hydroxy-6,6-diphenyl-2H-pyran-2-one (prepared in example AAA), 1.05 mmol of 2-isopropylbenzenethiol, and 1.05 mmol of piperidine in 20 mL of dichloromethane. The product was triturated with ether to afford a solid (m.p. 216-217° C.). 1H NMR (DMSO-d6) δ 1.17 (d, J=6.8 Hz, 6 H), 3.20 (m, 1 H), 3.77 (bs, 2 H), 5.64 (d, 1 H), 6.45 (t, 1 H), 6.92 (t, 1 H), 7.12 (d, 1 H), 7.32-7.48 (m, 10 H).
