Product 1

HCID 280292Aminopyrazine carboxamide

Procedure

A solution of 3-amino-pyrazine-2-carboxylic acid methyl ester (5.0 g, 33 mmol) in concentrated ammonium hydroxide solution (30 mL) was heated at 60° C. for 3 h. The mixture was cooled to RT and the resulting solid filtered. After thoroughly washed with water followed by ether, the title compound was obtained as a brown solid (3.7 g, 82%).
