Reaction Conditions

Reaction Steps

n-BuLi (2.5 M in hexanes, 17.0 mL, 42.5 mmol) was added dropwise to a solution of 1,4-dibromobenzene (10.04 g, 42.5 mmol) in THF (100 mL) at −78° C. under nitrogen. After stirring at −78° C. for 1 hour, 2-hexanone (4.5 g, 44.9 mmol) was added dropwise, and the solution was warmed to room temperature and stirred overnight. The reaction mixture was quenched with water and the organic layer was separated. Next, the organic phase was washed with water, dried over Na2SO4, and concentrated on a rotary evaporator to give a crude oil. The crude was purified by column chromatography (silica gel, chloroform) to give 6 as a colorless oil (10.0 g, 91% yield). 1H NMR (500 MHz, CDCl3) δ 7.45 (d, J=8.8 Hz, 2H), 7.30 (d, J=8.8 Hz, 2H), 1.79-1.75 (m, 2H), 1.68 (s, 1H), 1.54 (s, 3H), 1.24-1.28 (m, 4H), 0.85 (t, 3H).
