Sodium sulfate decahydrate → (1H-Indazol-3-yl)-N,N-dimethylmethanamine

Participants

Reaction Steps

Lithium aluminum hydride (13.7 g, 36.1 mmol) was suspended in THF (500 mL), and the suspension was added with a solution of N,N-dimethyl-1H-indazole-3-carboxamide obtained in Step 1 (34.2 g, 181 mmol) in THF (250 mL), followed by stirring at room temperature under the flow of nitrogen gas for 30 minutes. The reaction mixture was mixed with sodium sulfate decahydrate, was stirred for further 1 hour and was filtered through Celite. The solvent was evaporated under reduced pressure to obtain 3-dimethylaminomethyl-1H-indazole (24.2 g, 76%).
