YieldReaction ConditionsOperation in experiment
51% With hydrazine hydrate In 1,2-dimethoxyethane for 3 h; Reflux Step 2: To a solution of 6-bromo-3-chloro-2-fluorobenzaldehyde (1.0 g, 4.24 mmol) in DME (5 ml.) was added hydrazine hydrate (5 ml_). The mixture was refluxed for 3 hours and then cooled to room temperature. The solvent was evaporated, water (100 ml.) was added, and the organic product was extracted with ethyl acetate (3 x 30 ml_). The combined organic extracts were dried over sodium sulfate, filtered, and concentrated in- vacuo. The resulting residue was purified by silica gel chromatography to provide 4-bromo-7- chloro-1 H-indazole in 51percent yield. MS: 230.9 [M+H].
