Reaction Steps

1.485 g (4.03 mmol) of 1-(2-fluorobenzyl)-3-iodo-6-methyl-1H-pyrazolo[3,4-d]pyrimidine and 397 mg (4.44 mmol) of copper(I) cyanide were put in 11 ml of absolute DMSO and heated for 2 h at 150° C. After cooling, the reaction mixture was filtered on Celite and then washed with ethyl acetate and THF. The organic phase was washed with 25% aqueous ammonia solution, saturated aqueous ammonium chloride solution and saturated aqueous sodium chloride solution, dried over sodium sulphate and concentrated in a rotary evaporator. 994 mg (purity 81%, 75% of theor.) of the target compound was obtained.
