実験手順

Sodium (622 mg) was dissolved in ethanol (45 mL) and then 1-cyclopentyl-3-ethyl-5-amino-1H-pyrazole-4-carboxamide (3.0 g, 13.5 mmol), followed by ethyl 4-trifluoromethylphenylacetate (6.27 g, 27 mmol) were added. The reaction mixture was refluxed overnight, cooled to room temperature, and the solvent was stripped. Water, followed by 2N HCl were added to the residue and the product was collected by filtration, recrystallized from ether and dried at 110° C. and 0.2 mm Hg to afford 3.03 g of 1-cyclopentyl-3-ethyl-6-(4-trifluoromethylphenylmethyl) pyrazolo[3,4-d]pyrimidin-4-one, m.p. 212°-213° C.
