Reaction Steps

3.87 g of sodium methanolate and then 12.2 g (71.7 mmol) of phenylazomalononitrile (L. F. Cavalieri, J. F. Tanker, A. Bendich, J. Am. Chem. Soc., 1949, 71, 533) are added to a stirred solution of 21.92 g (71.7 mmol) of 1-(2-fluorobenzyl)-1H-pyrazolo[3,4-b]pyridine-3-carboxamidine in N,N-dimethylformamide from Example 6A. The mixture is stirred at 110° C. overnight and allowed to cool. The solid which precipitates is filtered off with suction and washed with ethanol. Drying results in 23 g (73% of theory) of the target compound.
