To a solution of 4-bromophenol (3.4 g) and 3-methylthio-1-propanol (2.6 g) in tetrahydrofuran (20 mL) were added tributylphosphine (7.5 mL) and 1,1′-(azodicarbonyl)dipiperidine (7.6 g), and the mixture was stirred at room temperature for 2 hr. The solvent was evaporated under reduced pressure, and the residue was purified by silica gel column (0% ethyl acetate/hexane to 20% ethyl acetate/hexane) to give the title compound (4.6 g, 83%) as a white crystal.
