Sodium Carbonate → 2-(6-Methylpyridin-2-yl)ethan-1-amine

Participants

Reaction Steps

28.5 ml (29.4 g, 586 mmol) of hydrazine monohydrate was added to a solution of 39.0 g (147 mmol) of N-[2-(6-methyl-2-pyridyl)ethyl]phthalimide obtained in the above step (1) in 300 ml of ethanol and the mixture was stirred at room temperature for 1.5 h. The mixture was poured into 300 ml of a saturated aqueous sodium carbonate solution. After extraction with chloroform, the organic layer was concentrated and the oily residue thus obtained was purified by distillation (75° to 80° C./0.01 mmHg). 12.6 g (yield: 63%) of the intended compound was obtained as a colorless oil.
