実験手順

5-{5-[[(Acetyloxy)imino](amino)methyl]-2-isobutoxy-3-pyridinyl}-2-methyl-3-propyl-2,6-dihydro-7H-pyrazolo[4,3-d]pyrimidin-7-one (Example 40) (55 mg, 0.13 mmol) was heated at 190° C. for 3 h. After cooling the oxadiazole was purified by flash column chromatography (elution with 50:1 dichloromethane:methanol) to give 21 mg of a yellow solid.
