Reaction Steps

To a stirred solution of ethyl 2-(4-hydroxyphenyl)acetate (20 g, 0.11 mol) in 200 ml of CCl4, was slowly added bromine (18.8 g, 0.11 mol) dissolved in 10 ml of CCl4 at 0° C. for 30 min. The reaction mass was stirred for another 30 min at 0° C. After completion of the reaction, the mixture was poured onto crushed ice and extracted with DCM (×2). The combined organic layers were washed with water, and 10% sodium bi-sulfite solution, dried over Na2SO4, filtered and concentrated in vacuo to give ethyl 2-(3-bromo-4-hydroxyphenyl)acetate in 78% yield. (22.4 g). 1HNMR (CDCl3): 7.42 (s, 1H); 7.14 (d, 1H); 6.97 (d, 1H); 5.53 (bs, 1H); 4.13 (q, 2H); 3.52 (s, 2H); 1.16 (t, 3H).
