Hydrazine → Isoquinoline-3-carbohydrazide

Participants

Reaction Steps

To a solution of methyl isoquinoline-3-carboxylate (10 g, 53.42 mmol) in ethanol (100 mL) was added hydrazine (17.1 g). The reaction mixture was refluxed for 30 min and concentrated under high vacuum to remove hydrazine. The resulting residue was triturated with ethanol (20 mL) to give isoquinoline-3-carbohydrazide (8.6 g, 86%). LRMS (M+H+) m/z 188.1.
