The synthesis of methyl 2-amino-6-methoxynicotinate, a valuable building block for the preparation of fused 2-pyridones, is reported. The optimized synthesis includes sequential microwave-induced regioselective 6-methoxylation, esterification, followed by microwave-induced reaction with p- methoxybenzylamine, and final deprotection under flow reaction hydrogenation conditions. Two key steps in the reported synthesis are a microwave-induced methoxylation and a microfluidic hydrogenation that afford improved regioselectivity and purity profile of the reaction products.

Various nucleophiles react with 2,6-dichloro-4-trichloromethylpyridine and 2-chloro-6-trichloromethylpyridine as expected, by displacement of ring chlorine atoms.But in the reactions of nucleophiles with 2,6-dichloro-3-trichloromethylpyridine and 2,6-difluoro-3-trifluoromethylpyridine, displacement of ring halogen atoms is accompained or followed by multiple attack at the trihalogenomethyl group.The reactivity of the trihalogenomethyl groups is modified by N-oxidation.A mechanism for the peculiar reactivity of the trihalogenomethyl groups is proposed, involving loss of halide ion from the CX3 group assisted by Ione pairs on substituents or negative charge in Meisenheimer intermediates.Both geometrical isomers of 1,2-dichloro-1,2-bis(2,6-dichloro-3-pyridyl)ethene are described.
