Abstract:2-Chloromethyl-4-ethoxylpyridine hydrochloride1 was synthesized starting from 2-methylpyridine through N-oxidation,nitration,ethoxylation,acylation,hydrolysis and halogenation to give 2-hydroxymethyl-4-ethoxylpyridine and was chlorinated by sulforous oxychloride and followed by salf formation which an overall yield of 20%,indicating that the method was suitable to industrialization because of simple operation,available raw materials and low cost. |
Key words:2-chloromethyl -4-ethyloxy pyridine hydrochloride;intermediate;synthesis |
