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 initially charged in 11 ml of absolute DMSO and the mixture was heated at 150° C. for 2 h. After cooling, the mixture was filtered through Celite and washed through 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 on a rotary evaporator. 994 mg (purity 81%, 75% of theory) of the target compound were obtained.
