3-(4-(benzyloxy)phenyl)-4-(pyridin-4-yl)furan-2(5H)-one → 3-(4-hydroxyphenyl)-4-(pyridin-4-yl)furan-2(5H)-one

Participants

Reaction Steps

A mixture of 3-(4-(benzyloxy)phenyl)-4-(pyridin-4-yl)furan-2(5H)-one (1.0 g, 0.002 mol) in 33% HBr/AcOH (50 mL) was refluxed for 3 h. The reaction mixture was quenched with a saturated NaHCO3 solution and extracted with EtOAc (2×50 mL). The combined organic layers were washed with water, dried over Na2SO4, filtered, and concentrated in vacuo to afford 3-(4-hydroxyphenyl)-4-(pyridin-4-yl)furan-2(5H)-one (0.7 g, 95%).
