The title compound was prepared as described in General Method 5 using 3.0 mmol of 5,6-dihydro-4-hydroxy-6-phenyl-6-(2-phenylethyl)-2H-pyran-2-one, 3.2 mmol of hydrocinnamoyl chloride, 3.2 mmol of triethylamine, and 30 mL of THF, followed by 30 mL of toluene and catalytic DMAP. Chromatography of the residue afforded 1.5 mmol of the intermediate 3-acyl compound. Reduction of this acyl derivative was accomplished with 3 mmol of sodium cyanoborohydride. The product was triturated from ether:hexane (1:5) to give the title compound (m.p. 68°-70° C.). 1H NMR (DMSO-d6) 2.20 (m, 2 H), 2.35 (m, 2 H), 2.42-2.59 (m, 4 H plus DMSO), 3.06 (q, 2 H), 7.00 (dd, 2 H), 7.07-7.43 (m, 13 H).
