실험 절차

A solution of 4-iodo-1H-pyrazol-5-amine (640 mg, 3.9 mmol, 1 equiv) and 2-(4-methoxyphenyl)malonaldehyde (700 mg, 3.9 mmol, 1.0 equiv) in ethanol (20 mL) was heated at 75° C. for 4 hours. The reaction mixture was allowed to cool to 23° C., and the precipitate was filtered, washed with cold methanol, and air dried to afford 3-iodo-6-(4-methoxyphenyl)pyrazolo[1,5-a]pyrimidine (2-1) as a white solid.
