3-Bromo-2-methylphenol (0.10 g), 3-(methylthio)propanol (0.055 mL), tri-n-butyl phosphine (0.12 g) and 1,1′-(azodicarbonyl)dipiperidine (0.15 g) are stirred in tetrahydrofurane for 16 hours. Water is added and the mixture extracted with diethyl ether. The organic layer is washed with brine, dried (Na2SO4) and volatiles removed under reduced pressure. The product (80 mg) is obtained after column chromatography (silica gel, n-hexane/ethyl acetate gradient 100:0 to 50:50).
