Reaction Conditions:

with dimethylsulfide borane complex in tetrahydrofuran at 0 - 20;

Steps:

Step 1

Step 1 : To a stirred solution of 3,5-dibromobenzoic acid (2 g, 7.168 mmol) in tetrahydrofuran (20 mL) was added borane dimethylsulfide (3.4 mL, 35.842 mmol, 5 eq.) at 0 °C, and the reaction mixture was stirred at room temperature for overnight. The reaction mixture was quenched with methanol at 0 °C and concentrated under vacuo to obtain (3,5- dibromophenyl)methanol as an off white solid (1.8 g, 94%). H NMR (400 MHz, DMSO-d6) δ ppm 4.47 (d, J = 6 Hz, 2H), 5.39 (t, J = 6 Hz, 1 H), 7.49 (s, 2H), 7.65 (s, 1 H).
