Procedure

To a solution of 200 mg (1.092 mmol) 3-amino-5-methoxy-pyrazine-2-carboxylic acid methyl ester in 4 ml THF was added 1.20 ml (1.20 mmol) i N sodium hydroxide and the mixture was stirred at room temperature for 29 h. To the mixture were added 1.09 ml (1.09 mmol) 1N HCl after stirring for 5 min toluene was added and the solvents were evaporated to provide the title compound together with sodium chloride as colorless solid. The mixture was used for coupling reactions without further purification.
