Participants

Reaction Steps

Following the procedure described for Example 4, 250 mg (0.411 mmol) (2E)-2-[(6-fluoro-3-methyl-1H-indazol-5-yl)methylidene]-3-oxobutanenitrile (Example 4A) were treated with 3-amino-4,4,4-trifluorobut-2-enenitrile. The crude product was purified by preparative RP-HPLC (aceto-nitrile/water gradient, final mixture 90:10 v/v) to yield 159 mg (42% of th.) of the racemic title compound.
