実験手順
A mixture comprising carbonic acid (1S,4R)-4-(2,6-dichloro-purin-9-yl)-cyclopent-2-enyl ester ethyl ester (Intermediate AA2) (1.00 g, 2.92 mmol), (1H-pyrazol-4-yl)-methanol (preparation shown below) (0.34 g, 3.50 mmol) and triphenyl phosphine (0.115 g, 0.44 mmol) in deoxygenated THF (10 mL) under an inert atmosphere of argon is treated with tris(dibenzylideneacetone)dipalladium(0) (0.13 g, 0.15 mmol) and stirred at 50° C. for 1 hour. The solvent is removed in vacuo and the crude product is purified by chromatography on silica eluting with MeOH/DCM (1:25) to yield the title compound.
