HCID 123876195-Amino-6-butylamino-4-chloro-2-methylpyridine-3-carboxylic acid, ethyl esterYield 72%

Procedure

By replacing 4-chloro-6-(1-ethyl)hydrazino-2-methyl-5-nitropyridine-3-carboxylic acid, ethyl ester in Example 1 c with 6-(1-butyl)hydrazino-4-chloro-2-methyl-5-nitropyridine-3-carboxylic acid ethyl ester, 5-amino-6-butylamino-4-chloro-2-methylpyridine-3-carboxylic acid, ethyl ester is obtained. Yield 72%, b.p. 200°-210°/0.01.
