2-Chloro-4,6-dimethyl-3-pyridinecarbonitrile → 2-Methoxy-4,6-dimethylnicotinonitrile

Participants

Reaction Steps

2-chloro-4,6-dimethyl-nicotinonitrile (2.5 g, 15.01 mmol) was dissolved in anhydrous methanol(70 mL), added with sodium methoxide (4.27 g, 75.03 mmol) at 0° C. and stirred for about 10 hours at nitrogen atmosphere. The above mixture was concentrated under reduced pressure and then neutrailized with a saturated solution of ammonium chloride and then extracted twice with 150 mL of methylenechloride. The resulting organic layer was dried using anhydrous sodium sulfate, filtered and concentrated. A silica gel column chromatography (20% EtOAc/Hexanes) was performed on the resulting residue and 2.41 g (99%) of 2-methoxy-4,6-dimethyl-nicotinonitrile was obtained in white solid.
