Reaction Steps

A mixture of bromide (1.3 g, 6.02 mmol, from step 1), 1-Cyclopentyl-2-propen-1-ol (1.14 g, 9.07 mmol), dichlorobis(triphenylphosphine)palladium (II) (85 mg, 0.12 mmol), sodium bicarbonate (0.61 g, 7.25 mmol) in N-methylpyrrolidinone (12 mL) was heated to 140° C. under N2 for 5 h. The reaction mixture was partitioned between 1N HCl and EtOAc. The organic layer was washed with saturated NaHCO3, brine, dried over Na2SO4 and concentrated to a brown oil. The oil was purifed by silica gel chromatography to give the title compound as a yellow oil (0.74 g, 47%). 1H NMR (CDCl3): δ ?1.17 (t, 3H, J=7.6 Hz), 1.54-1.80 (m, 9H), 1.17 (q, 2H, J=7.6 Hz), 2.73 (m, 2H), 2.84 (m, 2H), 3.80 (s, 3H), 6.75 (d, 1H, J=8.0 Hz), 6.97 (m, 2H).
