실험 절차

5-Amino-1-[4-(2-ethyl-5,7-dimethyl-pyrazolo[1,5-a]pyrimidin-3-ylmethyl)-phenyl]-3-methyl-H-pyrazole-4-carboxylic acid ethyl ester (16) (923 mg, 1.76 mmol) was dissolved in 15 ml of THF and after addition of isoamylnitrite (620 mg, 5.29 mmol) the reaction mixture was stirred for 12 h at 70° C. The reaction mixture was evaporated under reduced pressure and purified by chromatography (10-50% EtOAc in cyclohexane, 30 min) to afford a yellow solid.
