1.197 g (7.035 mmol) of ethyl cyclopentyl(oxo)acetate 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 concentrated and the residue was purified by preparative HPLC (mobile phase: acetonitrile/water with 0.1% TFA, ratio 45:55). This gave 749 mg of the target compound (26% of theory).
