Procedure
Following General Procedure A (125° C., 24 hours), 1H-pyrazole (102 mg, 1.5 mmol) is coupled with 4-iodoaniline (220 mg, 1.0 mmol). The crude brown oil is purified by flash chromatography on silica gel (eluent: dichloromethane/hexanes=50/50) to provide 90 mg (57% isolated yield) of the desired product as an orange solid.
