A mixture of 1.2 g of 2-[3-(2-oxopropylsufonyl)-4-n-propoxy-5-benzyloxy- phenyl]-5-(3,4,5-trimethoxyphenyl) tetrahydrofuran, 400 mg 10% Pd/C, 1-2 drops of acetic acid in 100 mL of ethyl acetate was stirred under H2 at 40 psi for 45 minutes. The reaction mixture was filtered over a bed of celite and evaporated in vacuo to yield the title compound: NMR(200 MHz, CDCl3) δ 1.10 (t, CH2CH2CH3), 1.92 (m, CH2CH2CH3), 1.9-2.6 (m, 3-CH2 & 4-CH2), 2.40 (s, CH3C(O)CH2), 3.86 (s, OCH3), 3.90 (s, 2 OCH3), 4.12 (t, OCH2CH2CH3), 4.42 (s, CH3C(O)CH2), 5.10-5.28 (m, 2-CH & 5-CH), 6.64 (s, 5-ArH), 7.35 & 7.47(2 d, 2-ArH).
