الإجراء التجريبي

A solution of N-[(E)-3-(3-methyl-4-oxo-1-n-propyl-1,5-dihydro-4H-pyrazolo[3,4-d]pyrimidin-6-yl)-4-n-propoxycinnamoyl]morpholine (0.5 g, 0.0011 mol) in ethanol (30 ml) was stirred with 10% palladium on charcoal catalyst (0.05 g) under a hydrogen pressure of 50 p.s.i. (3.45 bar) at room temperature for 14 hours. The reaction mixture was filtered and solvent removed by evaporation under vacuum. Trituration of the residue with diethyl ether, followed by crystallisation from ethyl acetate-hexane, afforded the title compound as white crystals (0.37 g, 74%), m.p. 132-133° C. Found: C, 64.39; H, 7.26; N, 14.80. C25H33N5O4 requires C, 64.22; H, 7.11; N, 14.98%.
