실험 절차

To a solution of (1R,3S,4S)-3-{[tert-butyl(dimethyl)silyl]oxy}-4-({[tert-butyl(dimethyl)silyl]oxy}methyl)cyclopentanol (973.5 mg, 0.002699 mol) in DMF (8.00 mL, 0.103 mol) was added NaH (202 mg, 0.00504 mol) (60% in oil). After stirring the mixture for 10 minutes, 2-chloro-4-nitro-pyridine (400.0 mg, 0.00252 mol) was added and the mixture was stirred overnight. The reaction was quenched with water and extracted with (3×50 ml EtOAc). The combined organic layers were dried (Na2SO4), filtered and concentrated in vacuo. The residue was purified by flash chromatography (0 to 10% EtOAc/hexanes) to obtain the title compound (0.9859 g, 83%) as a clear oil.
