Reaction Steps
In a 250 mL round bottom flask, 3-chloro-2H-indazole (1.95 g, 10 mmol), 30% HCHO (2 mL, 20 mmol) were mixed in water (10 mL). The reaction mixture was refluxed for 2 hours. After cooling down to room temperature, the solid was filtered, washed with water, and dried under vacuum to provide (3-chloro-2H-indazol-2-yl)methanol (1.82 g, 99% yield).
