Ammonia → 3-Amino-6-fluoropyrazine-2-carboxamide

Participants

Reaction Steps

In 1 mL of methanol was dissolved 10 mg of methyl 3-amino-6-fluoro-2-pyrazinecarboxylate. After adding 1 mL of 25% aqueous ammonia at room temperature, the mixture thus formed was stirred for 4.5 hours. After removing the solvent under reduced pressure, diethyl ether was added to the residue, and the deposited precipitate was filtered off. Thus, 4 mg of 3-amino-6-fluoro-2-pyrazinecarboxamide was obtained as a light yellow-colored solid product.
