Participants

Reaction Steps

51.82 g of 2-chloro-pyrid-6-one (400 mmol) and 12.7. g of 83% sodium-hydride dispersion in mineral oil (440 mmol) are reacted in 400 ml absolute dimnethylfomamide at room temperature under argon for 15 minutes. 32.4 ml methyl-iodide (520 mmol) are added dropwise and stirring is continued at 50° for 5 hours. The reaction mixture is evaporated on a rotary evaporator until the solvent starts to distill from a bath of 60°.
