Reaction Steps

To a solution of 4-bromo-2-methylbenzoic acid (1.0 g, 4.65 mmol) in Et2O (15 mL) was added lithium aluminiumhydride (370 mg, 10.23 mmol) and the mixture was stirred for 4 hours. The reaction mixture was diluted with water (100 mL) and extracted with EtOAc (4×100 mL). The combined organic fractions were dried (MgSO4) and concentrated in vacuo. The residue was purified by flash chromatography (silica, petrol ether/EtOAc) to give the title compound as a colorless gum (752 mg, 80%). 1H NMR (CDCl3, 400 MHz) δ 7.35-7.30 (2H, m), 7.24 (1H, m), 4.65 (2H, s), 2.32 (3H, s).
