Reaction Steps

610 mg (approx. 1.92 mmol, purity 86%) of 1-(2-fluorobenzyl)-1H-pyrazolo[3,4-d]pyrimidine-3-carboximidamide were initially charged in 10 ml of ethanol and cooled to 0° C. 777 mg (7.68 mmol) of triethylamine and 120 mg (1.920 mmol) of 80% hydrazine hydrate were added, and the mixture was stirred at room temperature for 18 h. The mixture was concentrated on a rotary evaporator, taken up in ethyl acetate and washed three times with saturated aqueous sodium chloride solution. The organic phase was dried over sodium sulphate, concentrated on a rotary evaporator and dried under high vacuum. 590 mg (purity 89%, 95% of theory) of the target compound were obtained.
