実験手順

To a solution of (1R,3S,4S)-3-{[tert-butyl(dimethyl)silyl]oxy}-4-({[tert-butyl(dimethyl)silyl]oxy}methyl)cyclopentanol (0.782 g, 0.00217 mol) in THF (30.0 mL) was added NaH (0.156 g, 0.00650 mol) and the mixture was stirred for 1 h. To this was added 2-amino-4-chloro-3-nitropyridine (0.376 g, 0.00217 mol) and the mixture was stirred overnight. The solution was concentrated and the residue was purified by flash chromatography (25% EtOAc/hexanes) to afford the title compound (0.381 g, 35%) as a yellow solid.
