참여 물질

반응 단계

To a 200 ml solution of 50 g of 5-bromo-2-hydroxy-3-methoxybenzaldehyde in an ethanol:THF=1:1 mixed solvent there was added 16.4 g of sodium borohydride while cooling on ice. After stirring for 2 hours at room temperature, 1N hydrochloric acid was added to the reaction mixture while cooling on ice. The organic layer was extracted with ethyl acetate and dried over anhydrous magnesium sulfate. The desiccant was filtered out and the filtrate was concentrated under reduced pressure to obtain the target compound (50 g) as a crude product.
