Reaction Steps

Cyclopentyl(5-fluoro-3-methyl-1-benzofuran-2-yl)methanone (27.15 g) synthesized above was dissolved in a mixed solvent of methanol (40 mL)-tetrahydrofuran (240 mL), and sodium tetrahydroborate (90%, 5.5 g) was added at 0° C. The reaction mixture was stirred at 0° C. for 2 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 (29.26 g, 100%) as a yellow oil.
