Versuchsvorschrift

To a solution of {(1S,2S,4R)-2-{[tert-butyl(dimethyl)silyl]oxy}-4-[(6-{[(1R,2S)-2-methoxy-2,3-dihydro-1H-inden-1-yl]amino}pyrimidin-4-yl)oxy]cyclopentyl}methanol (105.3 mg, 0.0002168 mol), N-Boc-sulfonamide (58.9 mg, 0.000300 mol) and triphenylphosphine (85.3 mg, 0.000325 mol) in EtOAc (4.15 mL) under an atmosphere of nitrogen was added diethyl azodicarboxylate (51.9 μL, 0.000330 mol). The mixture was stirred for four hours. The solvent was removed and the orange residue was purified by flash chromatography (10 to 50% EtOAc/hexanes) to obtain 135.2 mg (94%) of the title compound.
