-20 °C

To 140 ml of nitric acid are added portionwise, while maintaining the temperature at −20° C., 37.8 g (198 mM) of N-(4-propanoylphenyl)acetamide. The reaction medium is then poured into a water/ice mixture. The solid that precipitates out is filtered off and washed with water to give, after drying, 37.6 g of N-(2-nitro-4-propanoylphenyl)acetamide in the form of a pale yellow solid.
