Reaction Steps

0.817 g (7.035 mmol) of methyl 2-oxobutanoate in 15 ml of ethanol were initially introduced and heated to reflux. Then, 2.000 g (7.035 mmol) of 1-(2-fluorobenzyl)-1H-pyrazolo[3,4-d]pyrimidine-3-carboximidohydrazide suspended in 20 ml of ethanol were added and the mixture was heated under reflux overnight. After cooling, the mixture was filtered off with suction, and the filtercake was washed with a little ethanol and dried under high vacuum. This gave 1.83 g of the target compound (74% of theory).
