Procedure

In 5 mL of 25% aqueous ammonia is suspended 0.25 g of methyl 6-chloro-3-hydroxy-2-pyrazinecarboxylate obtained according to the method described in literature [J. Med. Chem., 285-287 (1969)]. The suspension is stirred at ambient temperature for 1 hour. The deposited crystals are collected by filtration to obtain 0.18 g of 6-chloro-3-hydroxy-2-pyrazinecarboxamide.
