반응 단계
Sodium (1.19 g) was dissolved in ethanol (85 mL) and 1-cyclopentyl-3-ethyl-5-amino-1H-pyrazole-4-carboxamide (5.7 g, 26 mmol) and then ethyl 3-methoxyphenylacetate (10 g) were added. The reaction mixture was refluxed overnight, cooled to room temperature and the solvent was stripped. Water was added to the residue, followed by 2N HCl and the precipitate which formed was collected by filtration and recrystallized from ethyl acetate to afford 5.08 g of 1-cyclopentyl-3-ethyl-6-(3-methoxyphenylmethyl)pyrazolo[3,4-d]pyrimidin-4-one, m.p. 148°-150° C.
