Participants

Reaction Steps

With ice cooling, 500 mg (3.43 mmol) of 4-fluoropyridin-3-ol hydrochloride were dissolved carefully in 3.2 ml of concentrated sulphuric acid, and 0.21 ml of concentrated nitric acid was added carefully at 0° C. The reaction was warmed to RT and stirred overnight. The mixture was added to 10 g of ice, and 6 ml of 45% strength aqueous sodium hydroxide solution were added dropwise with ice cooling. The solid formed was filtered off and then dried under reduced pressure overnight. This gave 191 mg (36% of theory) of the title compound.
