Reaction Steps

To a suspension of 2-chloroisonicotinic acid (18.0 g, 0.105 mol) in 250 mL of methylenechloride was added 1,1′-carbonyldiimidazole (17.0 g, 0.105 mol) portionwise. The mixture was stirred for 0.5 h and N,O-dimethylhydroxylamine hydrochloride (10.2 g, 0.105 mol) was added rapidly. The reaction mixture was stirred at room temperature overnight. Ether was added and the organic layer was washed with water, dried, dried over magnesium sulfate and filtered. The filtrate was concentrated to give 14.5 g (70%) of product as a yellow oil. This was used in next step without purification.
