Hydrazine → Pyridin-3-ylmethyl-hydrazine

Participants

Reaction Steps

To a solution of pyridine-3-aldehyde (5 g, 46.7 mmol) in methanol (100 mL) was added hydrazine (1.05 mL, 46.7 mmol). The reaction mixture was stirred at rt for 1 h. After purging with nitrogen, 10% Pd/C (200 mg) was added. The reaction mixture was purged with hydrogen and stirred under hydrogen at rt overnight. Solid material was removed, and the filtrate was concentrated to give a crude Example 85A. This material was used without further purification. Yield: 5.2 g (91%). MS (DCI): m/z 124 (M+H)+.
