Reaction Steps
Proceeding as described in Example 1, step 2, but replacing 2-(3-bromobenzoyl)acetonitrile with 2-(2-methyl-3-furanoyl)acetonitrile and substituting 4-fluorophenylhydrazine in step 3 with 2,4-difluorophenylhydrazine was obtained 5-amino-1-(2,4-difluorophenyl)-4-(2-methylfuran-3-oyl)-pyrazole (116).
