実験手順

A solution of 4,6-dichloro-5-fluoropyrimidine (102 mg, 0.61 mmol), (1R,3S,4S)-3-{[tert-butyl(dimethyl)silyl]oxy}-4-({[tert-butyl(dimethyl)silyl]oxy}methyl)-cyclopentanamine (200 mg, 0.56 mmol), and triethylamine (0.16 mL, 1.11 mmol) in ethanol (2.00 mL) was heated in a sealed tube under microwave irradiation at 140° C. for 1 h. The reaction mixture was concentrated under vacuum, and the residue was purified by flash chromatography (0 to 15% ethyl acetate/hexanes) to afford the title compound (213 mg, 70%) as a light yellow solid. LC/MS: Rt=2.60 min, ES+ 490.5 (AA standard).
