Reaction Steps

3-(5-chloro-2-methoxyphenyl)pyridin-4-amine (2 g, 8.5 mmol) was dissolved in 25 mL of acetic acid and 10 mL of THF at −10° C. To the solution t-butyl nitrile (2 ml, 17 mmol) was dropwisely added. The mixture was warmed to room temperature overnight. Water was added to the reaction mixture and was extracted by dichloromethane, the organic layer was then dried by MgSO4 and concentrated. The residue was then purified by column chromatography using THF:hexane (1:3, v/v) as the eluent. 0.8 g (46%) of product was collected as the product.
