Vorschrift

1-(5-Fluoro-3-methyl-1-benzofuran-2-yl)-2-methylpropan-1-one (11.66 g) synthesized above was dissolved in methanol (4 mL)-tetrahydrofuran (20 mL), and sodium tetrahydroborate (90%) (446 mg) was added to the solution at 0° C. The reaction mixture was stirred at 0° C. for 1 hr. Water was added to the reaction mixture, and the mixture was extracted with ethyl acetate. The organic layer was washed with saturated brine, and dried over anhydrous magnesium sulfate. After filtration, the filtrate was concentrated to give the title compound (1.193 g, 100%) as a colorless oil.
