Procedure

A mixture of 3-bromophenol (5 g, 29 mmol), 1-chloro-3-methoxypropane (4.33 g, 40 mmol) and K2CO3 (8 g, 57.8 mmol) in DMF (90 mL) was stirred at 100° C. for 2 h. the reaction mixture was filtered and the filtrate was evaporated in vacuo. The residue was taken up in t-BuME, and the organic layer was washed with aqueous NaOH (1N), water (50 mL) and brine. The organic layer was dried and concentrated to give 1-bromo-3-(3-methoxypropoxy)benzene (7 g, 99%). 1H-NMR (CDCl3): 2.02 (m, 2H), 3.33 (s, 3H), 3.54 (m, 2H), 4.02 (m, 2H), 6.82 (m, 1H), 7.11 (m, 3H).
