Facile and Efficient Synthesis of 4-Alkyl Derivatives of 3-Carbamoyl- and 3,5-Dicarbamoylpyridines as Nicotinamide Mimetics

[摘要]：Nicotinamide plays a key role in many biological processes and, as a consequence, its derivatives could be attractive for the synthesis of biologically active compounds. Here a rapid and efficient way of preparing alkyl derivatives of nicotinamide, precisely, 4-alkyl-3-carbamoylpyridine and 4-alkyl-3,5-dicarbamoylpyridine is reported. The synthetic route developed adopts mild reaction conditions and produces target compounds in higher yields compared with methods described in literature.
