Procedure
One operates as in Example 15, but the 4 parts of 1-cyano-1-methoxycarbonyl-3-methyl-4-amino-4-phenyl-2-aza-1,3-butadiene are replaced by 3.8 parts of 1-cyano-1-methoxy-carbonyl-4-amino-4-phenyl-2-aza-1,3-butadiene. 3.66 parts of 2-methoxycarbonyl-3-amino-5-phenyl-pyrazine are obtained. After recrystallisation of the product from methanol the melting point is 228°C.
