실험 절차

To a suspension of allyl 2-amino-6-(cyanomethyl)-pyrazolo[1,5-a]pyrimidine-3-carboxylate 4c (10.2 g, 39.65 mmol) in DCM (350 mL) was added phenylsilane (8.581 g, 9.773 mL, 79.3 mmol), followed by Pd(PPh3)4 (1.5 g, 1.298 mmol). The reaction was stirred at room temperature for 2 h. The reaction mixture was filtered and the solid was washed with DCM and dried under vacuum to provide 2-amino-6-(cyanomethyl)-pyrazolo[1,5-a]pyrimidine-3-carboxylic acid 5c as a yellow solid (8.61 g, 100% yield).
