Procedure
A nitric acid solution (HNO3>90%, 13.3 ml) is added slowly to a solution of oleum (H2SO4 containing 20% SO3, d=1.9, 10.5 ml) cooled to 0° C. 4-Pyridol nitrate (10 g, 63 mmol) is added, at 0° C., to the mixture, which is then heated at 90° C. for 1 h 30 min. The reaction mixture is poured over 50 g of ice. The suspension is stirred for 30 min at 0° C. and is then filtered. The solid is washed with a few ml of water and then air-dried. 6.59 g of product are obtained in the form of a white powder.
