Procedure

Under an argon atmosphere, 150 mg (purity 62%, 0.18 mmol) of 2-[1-(2-fluorobenzyl)-1H-pyrazolo[3,4-b]pyridin-3-yl]-4-iodo-5,5-dimethyl-5,7-dihydro-6H-pyrrolo[2,3-d]pyrimidin-6-one (example 15A) was suspended in 2 ml of absolute acetonitrile, and 304 mg (3.62 mmol) of 1H-pyrazol-4-ol, 118 mg (0.36 mmol) of caesium carbonate, 5 mg (0.04 mmol) of copper(I) oxide and 20 mg (0.15 mmol) of 2-hydroxybenzaldehyde-oxime were added. The mixture was heated in the microwave for 1 h at 200° C. The reaction solution was filtered and purified by preparative HPLC (eluent: acetonitrile/water with 0.1% formic acid, gradient 20:80→100:0). 20 mg (24% of theor.) of the target compound was obtained.
