Procedure

569 mg (2.313 mmol) of 3-iodo-1H-pyrazolo[3,4-d]pyrimidine and 828 mg (2.544 mmol) of caesium carbonate were initially charged in 10 ml of DMF, and 481 mg (2.544 mmol) of 2-fluorobenzyl bromide dissolved in 2 ml of DMF were added. The reaction mixture was stirred at RT overnight, diluted with 50 ml of water and filtered with suction, and the residue was dried under high vacuum. 733 mg of the target compound were obtained (purity 83%; 74% of theory).
