Reaction Steps

To a room temperature solution of 5-(4-hydroxyphenyl)-2,2-dimethyl-4-(pyridin-4-yl) furan-3(2H)-one (280 mg, 0.9 mol) in DMF (5 mL), K2CO3 (413 mg, 2.98 mol) was added and the reaction mixture was stirred for 30 min. 2-Chloro methyl quinoline (235 mg, 1.09 mol) was then added to the reaction and stirring was continued for 2 h at 85° C. The reaction mixture was then quenched with cold water and extracted with EtOAc (2×50 mL). The combined organic layers were washed with water, dried over Na2SO4 and concentrated in vacuo to obtain the crude product. The crude material was purified via silica gel column chromatography to afford 2,2-dimethyl-4-(pyridin-4-yl)-5-(4-(quinolin-2-ylmethoxy)phenyl)furan-3(2H)-one (240 mg, 57%) as a solid. 1H NMR (500 MHz, d6-DMSO): δ 8.58-8.54 (m, 2H), 8.42 (d, J=7.8 Hz, 1H), 8.04-7.98 (m, 2H), 7.80 (t, J=7.6 Hz, 1H), 7.68 (d, J=7.4 Hz, 1H), 7.64 (t, J=7.6 Hz, 1H), 7.58 (d, J=7.4 Hz, 2 H), 7.30-7.24 (m, 2H), 7.19 (d, J=7.2 Hz, 2H), 5.43 (s, 2H), 1.50 (s, 6H). MS: M+H: m/z=423.0. HPLC: 96%, (Condition-I).
