実験手順

In an autoclave, 3.40 g of 6-cyano-3,4-dimethylpyridine (25.7 mmol), 0.15 g of Pd/C (water-content=50%), 200 mL methanol and 3.0 mL concentrated hydrochloric acid are placed, stirred at room temperature for 3 hours while pressurizing with hydrogen to 3 atm. The reaction solution was filtered through Celite and the filtrate was concentrated to dryness. This was washed with methanol to give 2.41 g of 2-aminomethyl-3,4-dimethylpyridine (3,4-Me2PICA) hydrochloride (93% yield). This 2-aminomethyl-3,4-dimethylpyridine hydrochloride was treated with an aqueous solution of potassium carbonate to give 2-aminomethyl-3,4-dimethylpyridine (3,4-Me2PICA) quantitatively.
