Reaction Steps

To a solution of 10.7 g of LAH in THF (600 ml) was added dropwise a solution of 70.0 g of ethyl(3-bromo-4-methoxyphenyl)acetate in THF (200 ml) at an internal temperature of −12 to −3° C. After stirring at an internal of 0° C. or lower for one hour, Na2SO4/10 hydrate was added slowly. After foaming ended, filtration was carried out. The filtrate was concentrated under reduced pressure to obtain 45.0 g of the title compound (light yellow oil).
