To a stirred solution of 5-(4-hydroxyphenyl)-4-(4-methoxyphenyl)-2,2-dimethylfuran-3(2H)-one (600 mg, 1.93 mol) in acetonitrile (50 mL) was added K2CO3 (800 mg, 5.8 mol). 2-Chloromethyl quinoline (500 mg, 2.32 mol) was added dropwise under an inert atmosphere. The reaction mixture was stirred at 80° C. for 16 h and then partitioned between water and EtOAc (200 mL). The organic layer was separated, washed with water, dried over Na2SO4 and then concentrated in vacuo to obtain a residue. The residue was purified via silica gel column chromatography to afford 4-(4-methoxyphenyl)-2,2-dimethyl-5-(4-(quinolin-2-ylmethoxy)phenyl)furan-3(2H)-one (0.51 g, 58%) as a white solid. 1H NMR (500 MHz, d6-DMSO): δ 8.45 (d, J=7.2 Hz, 1 H), 8.02-7.97 (m, 2 H), 7.85-7.77 (m, 1 H), 7.76-7.68 (m, 2 H), 7.59-7.51 (m, 2 H), 7.19-7.11 (m, 4 H), 6.95 (d, J=7.4 Hz, 2 H), 5.41 (s, 2 H), 3.75 (s, 3 H), 1.45 (s, 6 H). MS: M+H: m/z=452.1. HPLC: 97%, (Condition-I).
