Abstract
Two 4-methoxy-2-N-alkyl carbamoyl pyridines were prepared from Williamson reaction between sodium methoxide and 4-chloropyridyl-2-formyl amide intermediates,which were synthesized starting from 4-chloropyridyl-2-carboxylic acid methyl ester,isopropylamine and butylamine.The effects of solvents and temperatures on the reaction were invisitigated.The structures of the compounds were confirmed by IR,1HNMR and ESI-MS.
