Reaction Steps

By substituting N-phenylpiperazine for N-methylpiperazine in Example 1 b and the resulting 4-chloro-2-methyl-6-(4-phenyl-1-piperazinyl)-5-nitropyridine-3-carboxylic acid ethyl ester is processed as described in Example 1 c-e, 7-methyl-5-(4-phenyl-1piperazinyl)pyrido[3,4-b]pyrazine-8-carboxylic acid ethyl ester is formed, m.p. 85°-87° (ligroin).
