Abstract
The present invention relates to a novel process for producing 2,3-diamino-6-methxoypyridine. The process comprises neutralizing 2,3-diamino-6-methoxy pyridine dihydrochloride, which, in turn, is prepared by the reduction of 2-amino-6-methoxy-3-nitropyridine. The 2-amino-6-methoxy-3-nitropyridine is further prepared by methoxylation of 2-amino-6-chloro-3-nitropyridine by sodium methoxide in methanol.
