実験手順

To a solution of 6-{[(1R,3S,4S)-3-{[tert-butyl(dimethyl)silyl]oxy}-4-({[tert-butyl(dimethyl)silyl]oxy}methyl)cyclopentyl]oxy)-8-iodo-9-(tetrahydro-2H-pyran-2-yl)-9H-purine (258.4 mg, 0.0003752 mol) in 1,2-Dimethoxyethane (3.0 mL, 0.029 mol) was added 7-chloroquinoline-4-boronic acid pinacol ester (0.158 g, 0.000546 mol), barium hydroxide (0.228 g, 0.00133 mol), water (0.5 mL, 0.03 mol) and Tetrakis(triphenylphosphine)palladium(0) (0.02 g, 0.00002 mol), and the mixture was heated at 90° C. overnight. The reaction was cooled, quenched by addition of water and the mixture was extracted with DCM (3×), washed with water, brine, dried (Na2SO4), filtered and concentrated. The residue was purified by flash chromatography (0 to 30% EtOAc/hexanes) to obtain 180 mg (66.2%) mg. Reference: Cammidge, A. N.; Crepy, K. V. L. Tetrahedron, 2004, 60, 4377-4386.
