Reaction Steps

At 0° C., potassium tert-butoxide (6.2 g, 55.4 mmol) was added to a solution of methyltriphenylphosphonium bromide (19.7 g, 55.4 mmol) in THF (180 ml). At from −10 to −5° C., 3-bromo-2-methoxy-6-methylsulfanylbenzaldehyde (12 g, 46 mmol) dissolved in THF (180 ml) was then added, and the mixture was stirred overnight at RT for 7 h. The mixture was filtered, and the solution was admixed with H2O (200 ml) and MTBE (200 ml) and then extracted with MTBE (200 ml). The combined organic phases were dried over MgSO4 and concentrated. Chromatography (cyclohexanez→cyclohexane/EtOAc 9:1) gave 1-bromo-2-methoxy-4-methylsulfanyl-3-vinylbenzene.
