Abstract:
A process for preparing an alkoxypyrazineamine derivative of the formula: ##STR13##in which R.sup.1 denotes hydrogen, alkyl or aryl, and R.sup.3 denotes alkyl or aryl, and wherein an alkoxypyrazine derivative of the formula: ##STR14##in which R.sup.1 denotes hydrogen, alkyl or aryl, R.sup.2 denotes --CONH.sub.2, and R.sup.3 denotes alkyl or aryl, and which is prepared by reacting a glyoxal derivative of the formula: ##STR15##in which R.sup.1 denotes hydrogen, alkyl or aryl with an aminoimidate of the formula: ##STR16##in which R.sup.2 denotes hydrogen, alkyl, --CONH.sub.2 or --COOR.sup.4 and R.sup.3 denotes alkyl or aryl, is reacted with an alkali metal hypohalite.
