Procedure

Analogously to the synthesis of Example 7A, 54.00 g (215.98 mmol) of 3-iodo-1H-pyrazolo[3,4-b]pyridine (synthesis described in WO 2006/130673 Example 4) were reacted with 50.18 g (237.578) of 2,3-difluorobenzyl bromide. Ice-water was added to the crude product, the mixture was filtered off with suction and the precipitate was washed with isopropanol and pentane and then dried under high vacuum. This gave 73.00 g of the title compound (85% of theory).
