Conditions

Temperature: 200 °C

Procedure

Under argon atmosphere, 200 mg (purity 62%, 0.24 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 2.5 ml of absolute acetonitrile, and 806 mg (4.82 mmol) of 5-(trifluoromethyl)piperidin-2-one, 157 mg (0.48 mmol) of caesium carbonate, 7 mg (0.05 mmol) of copper(I) oxide and 26 mg (0.19 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, gradient 20:80→100:0). 15 mg (11% of theor.) of the target compound was obtained.
