Methyl 4-cyano-2-methoxybenzoate → Methyl 4-(aminomethyl)-2-methoxybenzoate

Participants

Reaction Steps

A mixture of 4-cyano-2-methoxy-benzoic acid methyl ester (1.01 g, 5.28 mmol) in methanol (50 mL) was added to Raney-nickel 2800 slurry in water (a few grams washed with methanol to remove the water, Aldrich) and it was put under a 50 psi hydrogen atmosphere for 16 hrs. The mixture was filtered through Celite under an argon atmosphere and concentrated and then purified by flash chromatography to give 4-aminomethyl-2-methoxy-benzoic acid methyl ester (385.7 mg, 34.7%).
