Reaction Steps
2-Fluoro-5-nitroacetophenone (H. Sato et al, Bioorganic and Medicinal Chemistry Letters, 5(3), 233-236, 1995) (0.24 g) was treated with triethylamine (0.73 ml) and benzyl hydrazine dihydrochloride (0.255 g) in ethanol (20 ml) at reflux under N2 for 8 days. The mixture was cooled and the solid 1-benzyl-3-methyl-5-nitroindazole (0.16 g) was collected by filtration; m/z (M+1)+268.
