15.5 g (0.065 mole) of 3-methoxy-5-methylthio-4-propoxybenzaldehyde in 300 ml of methanol was cooled in ice bath. 1 g (0.026 mole) of sodium borohydride was added in 3 portions to the above solution. The mixture was stirred for 10 minutes in ice bath. MeOH was removed, and the residue was purified by flash column chromatography to afford 15.45 g (95% yield) of 3-methoxy-5-methylthio-4-propoxybenzyl alcohol as a light yellow oil.
