Reaktionsschritte
The named compound is prepared by substituting E & Z-3-[(hydroxy)-methylene]-6-fluoro-1,3-dihydro-indol-2-one for E & Z-3-[(hydroxy)-methylene]-1,3-dihydro-indol-2-one and 5-phenyl-1H-pyrazol-3-ylamine for 3-aminopyrazole in the reaction of Example 1. Specifically, E & Z-3-[(hydroxy)-methylene]-6-fluoro-1,3-dihydro-indol-2-one (0.033 gms.) is reacted with 0.065 gms. 5-phenyl-1H-pyrazol-3-ylamine by refluxing in tetrahydrofuran (0.88 mL) to afford the named compound in the amount of 0.0417 gms.
