反応手順
Trifluoroacetic acid (0.5 mL) was added to a methylene chloride solution (2 mL) of [(1R,2R)-2-tert-butyldiphenylsilanyloxy-1-(3,4,5-trifluorophenyl)propyl]carbamic acid tert-butyl ester (370 mg). This reaction solution was stirred at room temperature for 11 hr. To this reaction solution, a saturated sodium hydrogencarbonate aqueous solution and ethyl acetate were added. The organic layer was separated, washed with a saturated sodium hydrogencarbonate aqueous solution and then with saturated saline. Then, the organic layer was concentrated under reduced pressure to give 275 mg of the title compound. The physical property values of this compound were as follows:
