Participants

Reaction Steps

584 mg (3.103 mmol) of dimethyl 2,2-dimethyl-3-oxobutanedioate were initially charged in 12 ml of ethanol and heated to reflux. Subsequently, 590 mg (2.069 mmol) of 1-(2-fluorobenzyl)-1H-pyrazolo[3,4-d]pyrimidine-3-carboximidohydrazide suspended in 12 ml of ethanol were added and the mixture was boiled under reflux overnight. After cooling, the mixture was filtered, the filtercake was washed with a little ethanol and the filtrate was concentrated. The residue was stirred with 10 ml of acetonitrile. 188 mg of the target compound were obtained (purity 93%; 20% of theory).
