Reaction Steps

6-nitro-1H-indazole-3-carbaldehyde (500 mg, 0.003 mol) was dissolved in 50 mL THF. Lithium tetrahydroaluminate (400 mg, 0.01 mol) was added in 3 portions and the reaction mixture was stirred at room temperature overnight. Water (400 μL), 15% NaOH solution (400 μL), then water (1.2 mL) was added, and then the crystalline brown-yellow precipitate was filtered off. The filtrate was concentrate to an oil which was used directly in the next step without further purification. m/z=164.0. 1H NMR (d4-MeOH) δ 7.2 (1H, d), 7.05 (1H, d), 6.85 (1H, dd), 4.74 (2H, s).
