Reaction Steps

To a solution of ethyl 5-({[tert-butyl(diphenyl)silyl]oxy}methyl)-1,3,4-thiadiazole-2-carboxylate (998 mg) in methanol (12 ml) was added sodium borohydride (177 mg), and the mixture was stirred at 0° C. for 1 hr. A saturated aqueous ammonium chloride solution was added to the reaction mixture, and the mixture was extracted with ethyl acetate. The extract was dried over anhydrous magnesium sulfate and concentrated under reduced pressure. The residue was subjected to silica gel column chromatography, and the title compound (738 mg, yield 82%) was obtained as a colorless amorphous solid from a fraction eluted with ethyl acetate-hexane (2:1, volume ratio).
