Reaction Steps

A solution of DME (20 mL) and 2M Na2CO3 (15 mL) containing 3-bromobut-3-en-1-ol (1.40 g, 7.66 mol), (3-chlorophenyl)boronic acid (2.3 g, 14.7 mmol) and Pd(PPh3)4 (0.4 g, 0.35 mmol) was refluxed under an argon atmosphere for 3 hours. The solution was concentrated (to remove excess DME) and partitioned between water and ethyl acetate. The organic phase was washed with 1N NaOH, water (2×) and brine. The solution was then dried over MgSO4, filtered and concentrated. The residue was purified by silica gel chromatography using a hexanes/ethyl acetate gradient to give the title compound. 1H NMR (500 MHz, CDCl3): δ 7.42 (s, 1H); 7.31-7.29 (m, 3H); 5.43 (s, 1H); 5.21 (s, 1H); 3.73 (t, J=6.5 Hz, 2H); 2.77 (t, J=6.3 Hz, 2H); 1.91 (s, 1H). LCMS1 2.95 min. (M-OH)=165.
