一般描述

3-Chloro-6-methoxypyridazine undergoes regioselective metallation using various lithium alkylamides, temperatures and solvents (THF and ether). It was lithiated using lithium 2,2,6,6-tetramethylpiperidide during the synthesis of minaprine.

应用

3-Chloro-6-methoxypyridazine was used in the preparation of number of α-aryl-α-(pyridazin-3-yl)-acetonitriles.

This paper describes a modified method of preparation of a number of alpha-aryl-alpha-(pyridazin-3-yl)-acetonitriles via the C-arylation reaction of the corresponding carbanionsof phenylacetonitriles using 3-chloropyridazine derivatives. KOH and DMSO were used inthe deprotonation process, which made the reaction very simple and
