α-bromo-o-xylene (2.0 g, 10.81 mmol) was added to a solution of 2-methyl-phenol (1.06 g, 9.82 mmol) and cesium carbonate (7.99 g, 24.55 mmol) in DMF (20 mL). The reaction was stirred at 80° C. overnight. The reaction mixture was acidified with 25 mL 1N HCl(aq) and poured into copious water. The aqueous layer was extracted with ethyl acetate and the organic layer was dried (Na2SO4) and concentrated in vacuo. The resulting residue was purified via radial chromatography (20% ethyl acetate in hexanes) to yield 1.82 g (88%) of 2-(2-methyl-benzyloxy)toluene (31.1). LC/MSD m/e: 213.2 (M+H).
