Versuchsvorschrift

A solution of 6-chloro-3-iodo-1-(tetrahydro-pyran-2-yl)-1H-pyrazolo[3,4-b]pyridine-4-carboxylic acid ethyl ester (1.0 g, 2.30 mmol) and triethylamine (1.92 mL, 13.77 mmol) in THF (7.65 mL) was degassed using argon during 3 min. Cyclohexylacetylene (0.45 mL, 3.44 mmol), copper(I) iodide (0.08 g, 0.46 mmol) and tetrakis(triphenylphosphine)palladium (0.13 g, 0.11 mmol) were then added and the reaction mixture was stirred at room temperature overnight. The reaction mixture was concentrated under vacuum and the residue purified on a silica gel column chromatography using a gradient of ethyl acetate (0-5%) in cyclohexane to afford the title compound as a beige solid (0.93 g, 97%).
