Reaction Steps
(S)-3-(4-(3,4-Dichlorophenyl)piperidino)-1-(2-(5-ethoxycarbonyl-1,3,4-oxadiazol-2-yl)benzo(b)furan-4-yloxy)-2-propanol (1.3 g) obtained in Example 135 was dissolved in THF (20 ml) and lithium borohydride (60 mg) was added with stirring under ice-cooling. The mixture was stirred for 1 hr at room temperature, then poured into ice-water, and extracted with chloroform. The organic layer was dried over anhydrous sodium sulfate and concentrated under reduced pressure to give yellow crystals (1.2 g). The crystals were purified by silica gel column chromatography (chloroform/methanol) to give the title compound (100 mg) as pale-yellow crystals, melting point 158–160° C.
