反応手順
In 5.0 mL of methanol was dissolved 0.24 g of 3-azido-6-fluoro-2-pyrazinecarbonitrile. After adding 0.075 g of lead-poisoned palladium-calcium carbonate at room temperature, hydrogen gas was introduced into the mixture at room temperature under a pressure of 1 atmosphere until the mixture became showing no further adsorption of hydrogen. After filtering off the insoluble matter from the reaction mixture, the filtrate was concentrated under reduced pressure. The residue thus obtained was purified by silica gel column chromatography [eluent: chloroform] to obtain 0.078 g of 3-amino-6-fluoro-2-pyrazinecarbonitrile as a yellow-colored solid product.
