Participants

Reaction Steps

A mixture of benzyl 2-(3-hydroxyphenyl)acetate (1.39 g, 5.74 mmol), ethyl 4-bromobutanoate (1.23 g, 6.3 mmol), anhydrous K2CO3 (1.98 g, 14.4 mmol) and anhydrous DMF (10 mL) was stirred at room temperature overnight. Water was added to the mixture and extracted with ethyl acetate. The organic layer was washed with water, brine, dried (Na2SO4) and concentrated. The residue was purified by column chromatography on silica gel (ethyl acetate in petroleum ether, 25% to 50% v/v) to yield ethyl 4-(3-(2-(benzyloxy)-2-oxoethyl)phenoxy)butanoate (2.05 g, 100%) as a white solid. 1H NMR (400 MHz, DMSO-d6) δ 1.17 (t, J=7.2 Hz, 3H), 1.96 (m, 2H), 2.45 (t, J=7.2 Hz, 2H), δ 3.70 (s, 2H), 3.94 (t, J=6.4 Hz, 2H), 4.07 (q, J=7.2 Hz, 2H), 5.11 (s, 2H), 6.83 (m, 3H), 7.20 (t, 1H), 7.20 (m, 5H).
