Procedure
To a stirred suspension of 2-(4-(bromomethyl)phenyl)acetic acid (5.00 g, 21.8 mmol, 1.0 eq.) in methanol (75 mL) was added chlorotrimethylsilane (0.64 mL, 5.02 mmol, 0.23 eq.) at room temperature. The resulting mixture was stirred at room temperature for 2 hr, at which time the reaction was a clear colorless solution. The volatile material was removed under reduced pressure, the residue dissolved in methanol (25 mL), and the volatile material was removed under reduced pressure. This process was repeated two additional times to afford methyl 2-(4-(bromomethyl)phenyl)acetate as an orange solid (5.30 g, quantitative yield). 1H NMR (CDCl3, 500 MHz) δ 7.37-7.33 (m, 2H), 7.26-7.24 (m, 2H), 4.48 (s, 2H), 3.69 (s, 3H), 3.62 (s, 2H).
