実験手順

A mixture of ethyl (5-nitropyrazine-2-yl)acetate (6.7 g, 31.7 mmol) and Pd/C (1 g, 10%) in 300 mL of EtOAc was stirred at room temperature under hydrogen balloon for 6 hours before filtration. The filtrate was concentrated to afford ethyl[5-(hydroxyamino)pyrazin-2-yl]acetate (incomplete reduction).
