Versuchsvorschrift

A solution of methyl 2-formyl-3,4-dimethyl-5-(4-(1-methyl-1H-pyrazol-3-yl)benzyl)benzoate (0.09 g), (1S,2S)-2-aminocyclopentanol hydrochloride (0.03 g), triethylamine (0.03 mL) and anhydrous magnesium sulfate (0.06 g) in THF (1.80 mL) was stirred at room temperature for 46 hr under nitrogen atmosphere. The insoluble substance was removed by filtration, and the filtrate was concentrated under reduced pressure. The residue was diluted with methanol (1.80 mL) and THF (1.80 mL), sodium triacetoxyborohydride (0.10 g) was added thereto, and the mixture was stirred at room temperature for 7.5 hr. The reaction mixture was diluted with ethyl acetate, and the mixture was washed with water and saturated brine. The organic layer was dried over anhydrous magnesium sulfate, and the solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate/hexane) to give the title compound (0.04 g).
