Reaction Steps

4-Bromothiophenol (37.8 g) in N,N-dimethylformamide (200 mL) was treated with potassium carbonate (30.4 g) and cyclopropylmethyl bromide (29.7 g). The suspension was stirred at ambient temperature for 16 hrs then diluted with diethyl ether (500 mL). The organic phase was washed with water (2×500 mL), dried (MgSO4) and concentrated to give the title compound as an oil (46.4 g). 1H NMR (360 MHz, CDCl3): δ 7.38 (2H, d, J=8.0 Hz), 7.21 (2H, d, J=8.0 Hz), 2.83 (2H, d, J=7.0 Hz), 1.08-0.98 (1H, m), 0.58 (2H, q, J=5.1 Hz), 0.24 (2H, q, J=5.1 Hz).
