Reaction Steps
Pyridine (3.84 mL, 47.7 mmol) followed by bromoacetyl bromide (4.16 mL, 47.7 mmol) was added to a solution of 2-phenylpropan-2-ol (5.00 g, 36.7 mmol) in dichloromethane (100 mL) at 0° C., warmed to r.t. and stirred overnight. The reaction mixture was washed with water (3×100 mL), saturated aqueous sodium bicarbonate (3×100 mL), water (2×100 mL), dried (Na2SO4) and concentrated. The crude residue was purified by silica gel flash column chromatography (neutralized with TEA, heptanes) to afford the title compound (2.8 g (non-optimized), 30%) as a colorless oil. 1H NMR (300 MHz, ((CD3)2CO) δ: 7.44 (d, J=7.2 Hz, 2H), 7.34 (t, J=7.2 Hz, 2H), 7.25 (t, J=7.2 Hz, 1H), 4.01 (s, 2H), 1.78 (s, 6H).
